Ball Bearing Spring Washers

Ball bearing disc springs or ball bearing washers are designed for use with radial ball bearings as a retaining spring and are used to reduce vibration and shaft deflection. When used effectively, these disc springs reduce running noise and minimize excessive wear.

Ball Bearing Disc Spring Manufacturing

The BB and AK series disc spring are generally produced within our facilities using stainless steel with a Rockwell hardness testing score of C40-51. However, MW specializes in custom manufacturing, meaning that if your application requires specialty materials, finishes, or additional processes, we are happy to accommodate your needs.

Characteristics

These washers are designed as preloading springs for use with radial ball bearings and help to maintain positioning accuracy of the bearing while minimizing vibration and shaft deflection.

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.
