Slotted and Unslotted Ball Bearing Disc Spring

Our unslotted and slotted disc springs for ball bearings reduce noise and extend the service life of deep groove ball bearings.

Unslotted disc springs for ball bearings provide axial preloading of deep groove ball bearings, and can compensate for differences caused by dimension deviations.
In dynamic loading the disc springs absorb vibrations generated by deep groove ball bearings, and also result in noise reduction and extended durability of deep groove ball bearings.

Deflection of Ball Bearing Disc Springs
