Combination of rotary and rectilinear bearing

摘要

A combination linear and rotary anti-friction bearing. The bearing includes a casing within which is mounted a plurality of oblong tracks containing anti-friction balls adapted to engage a shaft and load bearing plates. Assembled to the casing at each terminal end thereof are rotary anti-friction balls mounted between outer and inner cylindrical raceway members so as to provide a linear and rotary bearing. The outer cylindrical members have a diameter slightly larger than the outer diameter of the casing.
