For the high stress requirements of automotive, locomotive, trucking, and heavy equipment components, BelleFlex® ball bearing disc springs are an excellent choice. Bellevilles are widely used in hydraulics, brake assemblies, train trucks, clutches, and transmissions, among other components.

Some applications in the transportation industry may use radial ball bearings. The rolling elements of radial ball bearings roll on two races, an outer race and an inner race. The use of Bellevilles to preload radial ball bearings helps to maintain position and minimize vibration by distributing the load evenly around the bearing race.  Shaft end play can undermine the performance of the ball bearing application, but the addition of properly preloaded Bellevilles will help to eliminate shaft end play and increase application life. 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.

BelleFlex® Belleville disc springs have a long life and are well-suited to sealed applications, such as transmissions. Available in materials, such as H13 Tool Steel, 300 Series Stainless Steel, and INCONEL® Alloys, BelleFlex® Bellevilles can withstand high temperatures, frequent cycling, and high loads. We also produce custom Bellevilles used in the automotive industry.
