Abstract
A ball-race shoe contains plural adjacent endless rows of rotating balls. Balls of adjacent rows are in mutual contact and are staggered with respect to each other to a longitudinal extent equal to the radius of a ball. The arrangement packs the balls as densely as possible so that, with dimensions comparable to those of known devices, both load-carrying capacity and useful life are optimized. A flat bevel or ramp in the inlet and outlet regions of the otherwise flat load-bearing support plate prevents short-period synchronization errors in the rolling action of individual balls of the ball-race shoe.
