Belleville Washer

Belleville washers are very compact spring washers that will allow your thermal assembly to expand and contract while still maintaining compressive force.

• Made from 302 Stainless Steel.
• For mechanical (compression) mounting method.
• Can be stacked in different ways to achieve greater force and more movement.
• Use a nested stack (parallel configuration) to increase load by the number of washers, but leave deflection equal to 1 washer.
• Use an inverted stack (series configuration) to increase deflection by the number of washers, but leave load equal to 1 washer.
• Also known as Belleville disc springs, spring washers
