Ball Bearing Disc Springs

Using Belleville disc springs to preload radial ball bearings helps to maintain positioning accuracy, eliminate shaft end play, and minimize vibration by distributing the load evenly around the bearing race. The bore holes of this series of spring are designed, so that the spring can preload the outer race of one size of ball bearing, as well as the inner race of another size of ball bearing.

The load values listed in the table below are according to the calculated theoretical load curve based on the dimensions and material for each part number.

Belleville disc springs are designed to operate within 20%-80% of their total available deflection. Misuse can result in premature fatigue failure. If your application requires the spring to operate outside of this range, our engineers can provide guidance or recommend an alternative solution.
