SN 1796, SN 1797/98
Balls made of highly wear resistant, hardened
ball bearing steel DIN 5401, are used as roll bodies.
The individual balls are arranged ring-shaped and
displaced, so that during stroke movements each
ball runs on its own way.
By rolling off of the ball between the guide pillar
and the guide bush the ball retainer makes a
movement. Herewith the stroke way s of the
ball retainer corresponds to the half tool stroke
(s ball retainer = 0.5 x s tool). From this results the
optimal length of the ball retainer L K, so that
the maximal possible number of supporting
balls is guaranteed.
