One application for disc springs is to preload bearings.

Disc Springs look like conically-shaped washers, a shape that lets them take an axial load. They can be used individually or assembled into stacks for a required deflection. Spirol Disc Springs’ performance characteristics are predictable, letting designers calculate a minimum life cycle. They also provide high levels of load/force in a small space, unlike other springs which require a significantly larger footprint to carry the same load. Their predictability, high reliability, and unparalleled fatigue life make the disc springs preferred over other types of springs in critical applications such as safety valves, clutch and brake mechanisms for elevators and heavy equipment, and supports for industrial pipe systems.

The two major updates to the newly expanded product line are larger sizes per DIN 2093 Group 2 (now available up to 250-mm dia.), as well as a full range of stainless steel Discs. Details are provided in the updated Disc Spring design guide.

The company’s Application Engineering team can assist with a best method of stacking the discs for the required force-deflection characteristic when multiple Disc Springs are required.
