Disc Spring Configurations
BB Series
BB (Ball Bearing) Series Disc Springs are specially designed as preloading springs for use with radial ball bearings. These disc springs help to maintain positioning accuracy of the bearing with no endplay. They also minimize vibration and shaft deflection. Proper preloading will increase bearing rigidity and eliminate excessive running noise.

AK Series
AK (Ball Bearing) Series Disc Springs are specially designed as preloading springs for use with radial ball bearings. These disc springs help to maintain positioning accuracy of the bearing with no endplay. They also minimize vibration and shaft deflection. Proper preloading will increase bearing rigidity and eliminate excessive running noise.
