Abstract:
Parallel ball bearing arrays are utilized in a pressure support means for a rack to reduce friction of a stationary pressure means supporting a moving rack in engagement with a drive pinion. The rack and a pressure pad have face to face coacting ball races on each side of the rack and so oriented that median planes of a pair of facing races are at an angle to the median plane of the rack. Accordingly, a train of balls on each side of the rack in the respective pair of coacting races has a median plane at an angle to the median plane of the rack on each side of the rack. Such orientation gives support normal to the rack and laterally as well, at the area where the rack engages the pinion.
