ABSTRACT:
An antifriction bearing bush which includes a thin cylindrical outer sleeve, a cylindrical ball retainer, and balls. The outer sleeve has an end wall and at least three equidistant axially extending convex portions formed on the inner surface thereof except for one end. The cylindrical ball retainer fits within the thin cylindrical outer sleeve and has at least three axially oblong grooves on the outside thereof. The oblong grooves are composed of two straight sections and two curved sections. One of the straight sections and an adjacent portion of each curved section is cut completely through the ball retainer. The straight section has extended straight sectional grooves reaching the ends of the cylindrical ball retainer. The depth of the straight sectional grooves are complementary to the convex portions on the outer sleeve. Two segments of the convex portion of the outer sleeve which overlie the ends of the straight section of the ball retainer are of less convexity than the remainder of the convex portion. The balls within one portion of the oblong grooves contact the convex portion and simultaneously extend beyond the inner surface of the ball retainer. Balls within the remaining portion of the oblong grooves are enclosed by the ball retainer and the outer sleeve. A circular groove is within the end of the sleeve not having an end wall to retain the ball retainer within the sleeve.
