Thrust Ball Bearing

Single direction thrust ball bearings

Description：

Single direction thrust ball bearings are a type of ball bearing specifically designed to accommodate axial loads in one direction. They consist of a shaft washer, a housing washer, and a set of ball bearings positioned between them. The shaft washer and housing washer have raceways on their surfaces to allow the balls to rotate freely.
