Belleville Washers

Belleville washers, also known as conical spring washers or disc springs, are a type of washer with a conical shape. They are used to provide a high spring force in a small space, making them ideal for applications where space is limited. Belleville washers can be stacked in series or parallel to increase the load capacity or spring rate.

These washers are commonly used in industries such as automotive, aerospace, and construction, where they are used to provide a controlled amount of tension or compression in bolts, screws, and other fasteners. They are also used in machinery and equipment where vibration or thermal expansion may cause loosening of fasteners.
