Precision ball bearing guide posts are manufactured from hardened steel to assure free rolling of balls and high wear resistance. Each post is drilled and tapped at the bottom for mounting of the ball cage washer assembly. This unique mounting method permits the ball cage, except when under pre-load, to freely rotate 360° around the guide post thus eliminating scoring or tracking of the guide post surface.
Demountable posts are tap fit and held in place with toe clamps and screws. They can be removed and assembled multiple times without damaging or distorting the mounting holes in the die set thus simplifying die building and maintenance. Demountable posts are also used to replace press fit posts when the press fit hole has been damaged and the straight pin no longer fits securely in the hole.
