Single Direction Thrust Ball Bearings

These bearings consist of one row of balls which rotate between a housing washer and a shaft washer. The housing washer is the thrust bearing’s equivalent of a radial bearing’s outer ring and is seating in the housing. It has a ball pathway machined on one of its sides (faces). The shaft washer is the equivalent of a radial bearing’s inner ring and is seated against the shaft. It also has a ball pathway machined on only one of its sides. As the name implies, this bearing should be used to accommodate a thrust load from one direction.
