Belleville Washers for Ball Bearings

To help maintain the positioning accuracy of a bearing, with no end play, our BB series disc springs are specially designed as preloading springs. Proper preloading will increase bearing rigidity and eliminate excessive running noise. They also minimize vibration and shaft deflection.

BB series disc springs are manufactured from C1075 Steel, with a Rockwell hardness of C40-51. Loads listed in our online catalog have a tolerance level of +/- 20% at .75h
