Belleville Disc Springs

Belleville Disc Spring Washers are stackable supporting devices that support a desired load or travel. When used singly or in stacks, Belleville disc washers provide numerous applicable advantages when a specific load or travel distance is desired. Disc spring washers withstand extreme temperatures as well as corrosive environments. Belleville disc springs function positively within conditions that require very high load in confined space or short travel. Disc spring washers conform to the European standards DIN EN 16983 & DIN EN 16984 and are RoHS compliant.

Belleville disc spring washers are available in Carbon Steel, 301 Stainless Steel, 17-7PH Stainless Steel, and Inconel 718.
