NAAMS Automotive Bushings


Demountable NAAMS bushings are self-lubricating and are available in guide post and pad styles. These bushings fully conform to the NAAMS, GM, Chrysler and Ford standards.

Self-lubricating bushings contain graphite plugs which are impregnated with oil. When the bushings reach 80-90°F as a result of friction between the bushing and guide post, oil is drawn from the plug, thus lubricating the wear surface. A dark smear pattern is created on the wear surface as the oil and graphite are embedded into the bronze or steel grain. This provides the lubrication necessary for continuous performance of the tool.
