DAYTools software includes a robust retainer design tool located in the lower right corner of the main screen.
The Multi-Position / Multi-Location retainer designer offers a few different ways to save your creation. Only the 3rd option allows you to re-load and continue to modify your creation.
- Exporting to CSV will create a comma-delimited text file of the features and dimensions used in your creation. Very few users can benefit from this format so Dayton discourages you from using this option.
- Export to CAD DATA offers several formats (DWG, STEP, IGES, DXF, etc). These files can be loaded into your design application.
- The most versatile Load and Save option handles "DAT" files. Dayton recommends that you always save your creation in the DAT format. You can export to CAD after you save an editable DAT file.
The DAT format is what you supply to your Dayton Distributor for pricing.

These easy-to-install self-contained strippers attach to standard catalog retainers with multiple spring pressure options. The compact robust design is ideal for newer high strength steels.
Cost-Effective Alternative to Custom Spring Strippers
Posi-Strip™ Features and Benefits
The Posi-Strip Punch Stripping System features a self-contained punch stripping unit for applications where large stripper plates or pads do not fit or cannot be shaped to custom contours. The compact, all-in-one design is a lower-cost alternative to custom built steel spring strippers. It is the ideal solution for holding material in compact spaces. Every punch can have its own designated stripper for more versatility and added flexibility within the die.
Each Posi-Strip unit utilizes its own custom spring, dependent on length and stripping force required. The soft bronze portion comfortably and closely encases the punch point for a clean stripping action that will not deform or damage the work piece during operation. The complete assembly is held together with a threaded backing plug that can be easily removed and restored without requiring special tools. With fewer assembly components, the self-contained unit minimizes the risk of lost items or tooling damage caused by displaced items.
Reduce setup and design time with an easily configured stripper. The small body and simple design make it easy to add to any die set that requires a unique punch stripping application.
A single product code gives you the stripper size, punch shape and force you need. The standardized catalog product code can be expanded to a custom contour defined in your CAD file, or you can order the stripper for your own in-house contour machining. This versatile product can be ordered as a standard catalog item, with no need to order as a special item.
Posi-Strip stripper units are easily paired to industry-standard Dayton punch retainers and can just as easily replace expensive strippers from other manufacturers. Posi-Strip is designed with a housing that mounts effortlessly to most industry standard retainers for a virtually unnoticeable footprint in the die.

Extend operating life with well-chosen Dayton Lamina die springs
Die springs, an essential stamping die component, create the optimal pressure for restraining the sheet material in a fixed position while it is being pierced, formed, flanged, or trimmed. The springs also provide controlled return pressure for the die stripper to permit the punches and other die-mounted tools to evacuate the material during the press' return stroke.
Die springs are most commonly used to actuate strippers, but they can also be found behind form pressure pads and binder rings in draw dies. The goal is to provide adequate die spring pressure within the limited remaining space of the die.
Spring Selection Process
To select a die spring, you first should gather information about three different aspects of the die design: how much pressure is needed; what spring size and how many are needed to produce that pressure; and how far these springs must collapse or travel.
To determine spring pressure for a spring used in a stripper, first calculate the perforating pressure for the entire die. To do this, you need to know the thickness and shear strength of the part material as well as the length of shear or cutting distance. These elements multiplied together will give you the perforating pressure. The formula reads:
Perforating pressure = S × T × L
- S = Shear strength of the part material
- T = Part material thickness
- L = Total length of shear or cutting distance
A pressure equal to 10 to 15% of the total perforating pressure typically is used to actuate the stripper (the range accommodates the potential differences among spring manufacturers). This allows for the downward ram speed to align safely and engage the die shoe components into their guided, mated components before material contact.
As the ram moves down, the stripper makes contact with the part material and stops. The spring continues to compress, or travel, until the ram reaches the bottom of its stroke.
Stripping pressure = Perforating pressure × 0.10 to 0.15
Although the formula for determining pad pressure in a form die is different from that of a stripper, it must still contain the same three elements of (1) pressure, (2) quantity and size of springs, and (3) the travel. The pad pressure in a forming operation should be at least 1.5 times greater than the force required for bending the part.
Bending pressure = ((S × 0.166 × T2) / (T + R1/2 + R2/2)) × L
- S = Tensile strength
- T = Material thickness
- R1 = Radius on form punch
- R2 = Radius on form die
- L = Length of form
Pad pressure = Bending pressure × 1.5
A forming operation requires more pad pressure than a bending operation because of the need to control sheet material movement over the forms and maintain its new shape. The pad pressure also helps to prevent material from scoring or tearing as it is being formed.
Pressure requirements for binder rings in draw dies tend to be less scientific, determined by trial and error. It is not uncommon to find a note on a draw die design stating the spring requirement as "springs to suit."
As the binder ring holds the material in its locating position, the spring pressure required tends to be adjusted to eliminate the tearing and shearing that may occur while the material is being drawn or stretched. A too-high spring pressure will inhibit the drawing of the material, while too little pressure will draw material up the form and fail to provide a uniform wall thickness.
Spring Size and Quantity
The amount of available space in the die will help determine how many springs to use and what sizes to choose. Whenever possible, try using numerous low-pressure springs rather than a few high-pressure springs. This will reduce stress on the springs.
As long as the tool layout permits the necessary space, more springs of lower pressure allow for more evenly distributed pressure and a more balanced stripper pad. This enhances sheet material control throughout the complete press stroke. Also, if just one die spring becomes fatigued, the die pad will continue to operate with the other springs.
Die spring placement, when applicable, should be nearest the area being pierced, formed, flanged, or trimmed. This enhances the ability to locate the most pressure on the area being worked upon while maintaining sheet material control. The use of spring cams, retainer bolts, or spring pockets serve to guard the springs from debris and protect the tool die details in the event of a fatigued or broken die spring.
When springs are installed in a die, they are compressed approximately 0.125 inch. Called preload, this compression is necessary to keep the springs from working their way out of the die. As a side benefit, the preload reduces the shock associated with rapid loading and unloading of the die and increases the spring life.
The bottom of the stripper draws up just short of being flush with the end of the punch. This ensures that the part material strips completely off the end of the punch. When the press cycle starts, the ram begins to move downward. The stripper makes contact with the part material and stops. As the ram continues descending, the springs compress, allowing the punches to extend through the part material and into the die button until the ram reaches the bottom of its stroke. This compression is called stripper travel.
The travel of a spring is determined by the spring preload, thickness of the material, entry of the punch into the die button, and the distance the stripper hangs below the bottom of the punch. Put simply, preload plus the stripper travel equals the total spring travel.
The same is true in form and draw dies. Pressure pads or binder rings will also travel and compress the springs. Preload plus travel of the stripper or comparable component will give you the total travel of the spring.
To reduce stress and allow for maximum spring life, you should keep preload and travel to a minimum. The more rapidly a spring works in compressing and decompressing, the greater the fatigue factor. Slower-spring applications permit longer spring travels, longer spring life, and the ability to operate near maximum spring deflection levels. The faster a die spring cycles, the shorter the spring life expectancy. In such fast cycling applications, you should lower the spring deflection.
Now that you know the pressure, approximate size, and travel, you can begin the actual spring selection process. This starts by combining the three aspects of the die design. First, divide the total stripping force required by the number of springs to be used.
The selected spring must deliver the desired pressure at preload. To determine the pressure of the spring at a given preload, multiply the amount of preload by the amount of pressure the spring develops over one inch. Most spring catalogs give pressure ratings over one inch as well as various other amounts of compression or travel.
Keep in mind that the spring must offer sufficient travel within its normal operating range. For example, the maximum operating range of a medium-pressure spring is approximately 50% of the free, or static, length. The efficient operating range of this spring is between 10 and 35% of the free length. Higher-pressure springs will have a shorter range of travel.
Although springs will compress beyond the maximum operating range, you should avoid this at all cost. Compressing beyond maximum range will severely hinder spring life and could damage the die. It is also a good idea to choose a spring with extra travel to prevent over-traveling the spring after a tool has been re-sharpened.

Perforating holes through one side of a round tube can present several unique problems for metal stampers. The most common are tube deformation, punch point chipping, and slug control.
Tube Deformation and Punch Point Chipping
The first two problems, tube deformation and punch point chipping, are typically caused by tube movement. A nesting die can be used to reduce this movement. The ideal nest should be a radius pocket that is machined a few thousandths of an inch larger than the outside diameter (OD) of the tubing. This will help locate the tube and offer some lateral support.
The depth of this nest should be slightly more than one-half the OD of the tubing to minimize tool marks and reduce tube deformation.
In addition to proper nesting, it is equally important to lock the tube into position using a "V" groove in a spring stripper. A "V" groove with a 60- to 80-degree included angle will prevent tube rolling and offer additional lateral support. Without this die and stripper support, the tube will be deformed while the hole size will be inconsistent and out-of-round.
The third major concern when perforating tubing is slug control. Slugs that do not break free in manufacturing may interfere with mating parts at assembly or break free and rattle around in the part while in use—neither of which is desirable.
One approach of solving this slug problem is to put shear on the point of the punch. Shear angles and contours play a major part in slug control when perforating a hole without a matrix. They minimize the deformation of the tube by preventing the slug from pulling to one side of the hole as the punch penetrates the tube wall.
Several different shear configurations can be applied, some of which are limited to specific types of tubing materials.
A concave shear that nearly matches the OD of the tube works well for ridged plastics and thick-wall aluminum tubing. It locks the slug into place and cuts it free.
Be aware that the two feathered edges are prone to breakage, and wear prematurely. In more severe applications, the feathered edges of a convex shear will chip and the punch may split up the middle.
A flat-bottom punch will work on mild steels. Although not typically considered a shear angle, a flat bottom punch will have a shear effect reducing deformation when perforating contoured material.
One drawback to a flat-bottom punch is that it does not prevent the slug from pulling to one side. This setup may leave an occasional slug partially attached to the tube.
The most effective shear configuration is a two-dimensional convex radius that is slightly larger than the OD of the tube. It reduces tube deformation while offering good slug control. A positive side effect from this configuration is that it reduces punch-point chipping, making it ideal for stainless steel and thin-wall tubing applications.
Another method of slug control is to not remove the slug at all. By piercing instead of perforating, the excess material from the hole is rolled over or formed down into the hole, leaving no free slug to contend with.
This method of slug control is accomplished by using steep shear angles on the point of the punch. The punch will have three or four flats ground on the point similar to that of a nail. The angle should be between 20 and 60 degrees included.
These shear angles are the result of development (trial and error). Changes in the shear angle will have a direct effect on how much the tube will be flattened or deformed. These angles are limited by how far the tip of the punch can enter through one side of the tube and not contact the opposite wall.
Steeper angles will produce the least amount of deformation, but will be more likely to contact the opposite wall. This type of pierce is most effective when working with aluminum or mild steel.
These are the most common shear configurations. However, many others have been developed and will also work well.
When perforating tubing on a stamping press, please consider the above recommendations. They are sound methods for reducing current problems and will serve as a good foundation for further development.
Perforating tubing through both sides, at an angle, or with a mandrel are considerably different circumstances, all of which are topics in themselves.

Standardized Perforating Tools
- Highly Standardized
Dayton Kommercial (inch) and Press Fit (metric) products are the economical answer for basic single station and progressive dies not requiring the precision of Versatile. Punches, buttons, and retainers are highly standardized to provide maximum economy.
Dayton's TuffPunch® offers heads-above-the-rest performance with durable, long-lasting punches and punch blanks.
TuffPunch punches and punch blanks are Kommercial quality products manufactured with thicker, larger, and 10° angled diameter heads, and are designed to reduce punch load and significantly lower failure rates when using heavy gauge and high tensile material. TuffPunch products are well-suited for high-demand industries where frequency and heavier-than-normal impact punching activity occurs and where optimum performance is required.
Unique Head Design:
All Dayton TuffPunch products are designed with a 10° angled head with a diameter equal to the shank diameter. This design allows the perforating forces to travel up from the shank and completely through the head. This eliminates the lateral shock waves that would otherwise put stress on the outer edge of the head, resulting in frequent failures - especially in heavy-duty applications. In addition, Dayton TuffPunch products are available in common shear angle configurations to reduce punch load and minimize the risk of slug pulling. Shear angle configurations include: chamfer, conical, double shear, and single shear.
TuffPunch® Retainers give you true dimensional accuracy each and every time!
Dayton True Location™ Retainers — the recognized industry standard — are now engineered for TuffPunch tooling. With all the features of the original True Location™ Retainer, this new retainer is designed to maximize the performance of your TuffPunch tooling. All TuffPunch® Retainers are available in both inch and metric sizes.
Ultimate Performance. Ultimate Value.
EVERLAST® is a state-of-the-art, *proprietary process that alters the structure of the tool steel at the molecular level, creating a metal fabricating tool typically lasting 3 to 5 times longer than an untreated tool.
It can be used in all applications, including: stainless, AHSS and UHSS, Martensitic, cold rolled, rail, boron, and others. In addition, it can be applied to a wide variety of tool types—extending the service life of the tool.
EVERLAST® is not a coating and not a heat treatment. It can be applied with or without additional secondary processes, such as coatings. It can be used with all Dayton punches, pilots, die buttons, special die sections, etc. The end result:
- slower wear rate
- longer tool service life
- more consistent part quality
- more uptime
EVERLAST® does not alter the surface appearance nor change the machinability of the metal. Dayton punches, punch products, and cutting surfaces altered from EVERLAST® are, in fact, easily resharpenable.
EVERLAST® can be applied in processes and applications where the primary mode of failure is chipping, micro-chipping, and/or chipping leading to wear. (See test results.)
Use with coating and other modifications
EVERLAST® is an enhancement that is independent of secondary processes, including: coating, edge modifications, and heat treatment. It can be used with virtually any tool steel grades without affecting the positive results of the conditioning or treatment of the steel.
Stamp with Confidence
Dayton Lamina tested EVERLAST® extensively through both real world and laboratory tests—initially, to delay micro chipping in piercing tools. In addition to delaying chipping, tooling service life increased significantly, based on the stamping application.
Over an extended period, Dayton Lamina field-tested more than 1,000 tools enhanced with EVERLAST®. The following are some of the results of those tests.

Closed End Punch Strippers
Closed End Urethane Strippers assure positive stripping and at the same time dampen punch vibration by gripping around the punch point. Since vibration can lead to premature punch failure, using DAYTON PROGRESS Urethane Strippers will increase overall punch life. The closed end feature holds thin stock flat during the stripping cycle, eliminating the problem of damaging the stock strip.
And that's not all...
Because of a unique curing agent, DAYTON's Urethane Strippers develop more load-bearing capacity than similar urethanes. This special curing agent also contributes to consistent pressure ratings.
SMART-Strip™ Hard Face / Dual Durometer Urethane Strippers
A DAYTON PROGRESS Exclusive
- Stamping shapes in thin material?
- Stamping pre-painted material?
- Short runs?
- Piercing on angles or complex contours?
- ...Any application where using a metal spring stripper is problematic or just not cost effective.
The answer is the new SMARTStrip. Available only from DAYTON PROGRESS.
The body of the closed-end punch stripper is made of fl exible, softer urethane elastomer 95A, enabling defl ections up to 15%.
The 75D durometer hard face is elastic, durable and does not mark the surface of the sheet metal or prepainted material.
The SMARTStrip works similar to a metallic spring stripper plate that is machined to match the face of the punch tip.
Unlike strippers that have a piece of plastic or metal glued to the end, the hard face on the SMARTStrip can not separate from the body.
- Designed to comply with NAAMS™ (North American Automotive Metric Standard) & FORD World Standard.
- The headed design prevents the strippers from falling into die.
- Fits most makes of standard retainers for head type and ball lock type punches. Standard durometer: 95A
- Ideal for punching odd shaped holes.
- Assure positive stripping.
- Increases punch life, as punch stripper supports the punch tip, by dampening the vibration of the punch, as it pierces the sheet metal.
Sheets, Rods & Bars
Urethane bars are specially-molded die-pads for press brake bending applications. Rods are used as strippers, pressure cylinders, in bulging applications, as tube bending mandrels, & for machining.
Advantages of urethane springs, open end strippers and tubes:
- High pressures
- Closer center distances
- High tear resistance
- Oil resistant
- Punch vibration dampening
- Easy installation and replacement - No need for set screws or stripper bolts
- No shrapnellizing (flying to pieces, when fractured under load) thus preventing injury to worker and damage to the die.
- Conventional heavy duty die springs obtain up to 500 lbs. per 1/8” deflection, compared to 2600 lbs. per 1/8” deflection on urethane springs.
High load-bearing capacity, extraordinary toughness and high impact resistance characterize Dayton NAAMS™ compliant strippers. These features provide high stripping pressure, minimize abrasion and provide excellent wear resistance. The urethane compound prevents marring of metal surfaces and is perfect for pre-painted materials where the integrity of the surface can not be compromised.
Dayton Progress Corporation is certified ISO 9001:2008. The ISO 9001:2008 certification exemplifies Dayton's continued commitment to enhance customer satisfaction through quality management practices and standards.
This certification by no means represents the end of the process, rather it strengthens our resolve to keep raising the bar on customer service. Achieving ISO 9001:2008 certification validates Dayton's continued commitment to global quality and complete customer satisfaction.
Dayton EZ Fit Ball Lock Retainer Inserts give you the ability to reconfigure and custom-make retainers in-house as die specifications change. The unique single-piece teardrop shape, combined with both a straight and an angled wedge side, holds your ball lock punch securely in place. EZ Fit Inserts reduce cost and downtime - and simplify tooling changeover.
With EZ Fit Inserts you can replace a damaged punch hole but with the competitor’s round insert you cannot. A damaged punch hole means a new retainer unless you use Dayton’s EZ Fit Insert.
Build New or Modify Existing Retainers — Quickly & Easily
The Dayton EZ Fit™ Inserts provide a simple, low-cost solution to building new dies because the inserts utilize a revolutionary design that assures a positive, rigid, and more accurate fit than other inserts on the market.
One side of the insert is cut at an 8° angle to create a wedgeshape that — when combined with the teardrop shape — assures that the insertand retainer fit together as a single unit.
EZ Fit™ Inserts are also ideal for repairing or making engineering changes. When changes occur — and the location(s) of the punches in the die set change(s) — new or reconfigured retainers are required. In-house modification can slow the changeover process; often requires specialized equipment and knowledge; and the integrity of the original retainer can be compromised.
Now — with the help of the all-new Dayton EZ Fit™ Ball Lock Retainer Insert — building new or repairing/retrofitting existing retainers can be simplified and completed in-house at a fraction of the cost of replacing existing retainers!
Dayton EZ Fit™ Retainer Inserts can be used to change hole locations in Multi-Position™ Retainers, thus allowing reuse of existing retainers. The process is quick, easy, effective, and far less expensive than part replacement costs. To retrofit, simply wire cut the hole to the specified size. Wire cut EDM instructions are included with each insert, and can be downloaded below.
Tighter Tolerances. Optimum Performance.
Dayton EZ Fit™ Inserts are designed to assure tighter, more precise tolerances than other retainer inserts.
The EZ Fit™ unique teardrop shape provides a single, tightly secured receptacle for the punch. One side of the piece (the flat side) is cut at an 8° angle to create a wedge shape. The hole in the retainer is wire cut to create a snug fit.
Wire Cut EDM
Each insert comes complete with wire cutting instructions that show recommended dimensions and tolerances for optimum performance. Wirepath information is available for download in DXF and DWG formats:
(*Light Duty Metric is discontinued. Some sizes available. Call for availability.)
For in-die stamping numerical data on parts
Available in 4 and 6 wheel units
The CUMSA Marking Unit from Dayton Lamina features 3.8mm (.150") tall easy to read numbers to mark parts with date, part number, lot number or other numerical identifiers. Each wheel features numbers "0" thru "9" plus a blank providing multiple combinations. Available in 4 and 6 wheel configurations, it is a simple process to change the numbers in the self-contained unit.
The unit can be surface mounted in a die, mounted in a pocket, even cam mounted if you have an angular surface. Depth of penetration of the number can be adjusted by grinding or shimming the hard bottom plate of the unit. This allows for proper control of the appearance of the numbers when dealing with different materials.
The CUMSA number wheels are made of tool steel and fully hardened for a long service life. In the event a new wheel is needed, the change is a simple process.
- Traceability for sheet metal parts
- Available with 4 and 6 wheels
- Quick and easy change of wheel's position without removing from the die

PosiLoc® True Position® retainers guarantee true dimensional accuracy.
Dayton's PosiLoc® Positive Locking Mechanism is designed to eliminate "ball bouncing" in retainers. Bouncing can occur in ball lock retainers because of the impact generated from the new high strength steels—even when heavy-duty springs are used. The bounce typically does not affect the stamping operation at normal levels. However, in high-demand punching—especially when high strength, lighter weight steels are used—bouncing can have a negative effect on punching accuracy and tool life. The Dayton PosiLoc® locking feature is a modification to existing Dayton True Position® Retainers. It prevents the bounce with the help of an adjustable angled setscrew to create a positive lock against the punch by "locking" the retainer ball in position. Dayton Ball Lock Retainers with the PosiLoc® feature also allow punch replacement without disassembly of the die, thus making tool changeover quick and easy.
The hardened backing plug acts as a head on the punch much like press fit punches, but actually produces more support for the load than a press fit punch of the same size. The backing plug is precision ground with the in-line dowel accurately located on the centerline of the punch.
The hardened backing plate has the same function as the backing plug. That is to prevent the punch from sinking into the upper die on impact. Backing plates spread the load over a larger area for very demanding applications where extreme pressures are being exerted and you are looking for extra insurance to minimize sinking into the upper die.
Retainer sets include:
- Ball Release Set Screw
- PosiLoc Screw

Highly Stable, Resilient.
Dayton's DAYLube™ NanoCeramic Lubricating Grease is a leading edge, extremely high-performance lubricant that has a wide range of industrial applications. DAYLube™ utilizes nano ceramic particles that act as sub-microscopic "bearings," providing continuous lubrication to steel surfaces. DAYLube™ gives you ten times the normal life, a much lower coefficient of friction at all temperatures, extraordinary adhesion, and higher load-bearing properties than traditional high-performance greases.
DAYLube™ is a high-performance, highly stable lubricant that delivers unmatched performance, durability, and wear resistance.
DAYLube™ outlasts PTFE greases in the same applications by ten times due to its lower friction coefficient and its ability to operate at a wider range of temperatures!
Nano ceramic particles-the key component-offer a lower coefficient of friction at all temperatures.
DAYLube™ has high load-bearing properties; a low dielectric constant; does not contain metal or silicone; and is resistant to water, steam, acids, and most chemical products. All of this gives DAYLube™ greater staying power, even under intense pressure and temperatures.
- Staying Power-extraordinary adhesion extends production to 10 times that of other greases.
- Shear Stability-does not soften or run out. After 100,000 production strokes, shows no evidence of breaking down.
- Operating Temperatures-operates in a normal range from -40° F to +800° F, plus ceramic particles remain intact up to 2500° F.
- Extreme Pressure & Anti-Wear Protection-resists EP, provides exceptional stability without using lead, antimony, chlorine, zinc, barium, etc.
- Corrosion Resistant-resists water, steam, acid, and other chemicals.
- High Dropping Point-maintains viscosity across full temperature range.
- Low Coefficient of Friction-lower than PTFE greases.
- Chemically Inert-environmentally friendly.
- Low Dielectric Constant-excellent insulator.
- Resilient-upon cooling returns to original viscosity after reaching dropping point.
A Better Way. A Better Value.
DAYLube™ is an extraordinary, state-of-the art lubricating grease. It provides exceptional friction reduction and wear resistance, and outlasts and outperforms virtually all other lubricating greases on the market.
It is also the best value on the market today.
When compared with the price of our closest competitor (using nanotechnology), the per ounce cost for DAYLube™ is considerably lower. Also, traditional PTFE lubricants are priced lower; however, the real value can be found in comparing the real life of the lubricants and considering the additional cost of maintenance and downtime.
DAYLube™ remains on the surface longer, extending production up to ten times that of PTFE lubricants. Further, DAYLube™ has much greater shear stability than other lubricants. In laboratory and on-site tests, the change in penetration after 100,000 strokes is low-meaning the grease did not soften under shear. Both longer run times and greater shear stability mean less total product cost, less maintenance, and far less downtime for lubricating.
In addition, DAYLube™ operates in a far wider range of temperatures than traditional lubricants, making it more versatile than PTFE products. For all practical purposes, you simply cannot purchase PTFE lubricants that will operate in this wide temperature range. Also, it is environmentally friendly.
Dayton products represent the best of the best, offering both top quality and outstanding value. DAYLube™ is no exception.
DAYLube™ NanoCeramic Lubricating Grease is ordered by quantity and product numbers. DAYLube is available in 16 oz. tubes, 16 oz. jars, 1 gallon or 5 gallon bucket. 16 oz. tubes and jars can be ordered individually or by the case.

Nanotechnology involves the development of materials, devices, and processes at the molecular level. In recent years, scientists have learned to fabricate molecules based on individual, task-specific designs. Today, nanotechnology is being used more and more to develop new, better, and more cost-effective products. One of those products is DAYLube™.
DAYLube™ - The Ultimate in Machine Lubrication
Key components in DAYLube™ are nano ceramic "bearings" that have an affinity for steel, and provide continuous lubrication at the surface. These are fabricated over a calcium sulfonate thickener within a mid-viscosity petroleum-based paste.
ASTME 4-Ball Weld Test
In laboratory tests, DAYLube™ performed extremely well over both standard greases and other so-called "high-performance" lubricants. The following criteria were used:
- 3 ball bearings submerged in grease
- 500kg pressure applied to center bearing
- center ball bearing spun at 10,000 rpm
- 10 seconds with "no weld" passing grade
In standard grease tests, results showed an instant weld and catastrophic failure of all 4 bearings. In tests with competitive brands, a soft weld occurred after 2 seconds, and there was a complete failure and major damage to all bearings.
Tests with DAYLube™ showed no weld after 10 seconds and minimal damage to all ball bearings.
