Spring washers are used in high load bearing bolted assemblies to maintain distance between parts of machinery or to add flexibility as well as allow thermal expansion and vibration.
These springs make it possible to compensate for settling in the threaded connections and thus to avoid slackening or loosening of the connection.
They are able to withstand static loads continuously or intermittently, or be subjected to dynamic loads continuously.
These Belleville washers can be used singly or stacked in parallel, in series or in a mixed configuration.
They are made from steel which provides excellent corrosion resistance and have a standard surface treatment, phosphated and oiled, which protects well against humidity and occasional mold.
These spring washers are stressed for their greater resistance to fatigue, their intrinsic damping capacity and their flexibility in the arrangement of the stacks.
