Conical Washer (Belleville)

Conical washers, also known as Belleville washers, are disc-shaped spring washers designed to provide high load capacity with minimal deflection. Their conical shape allows them to act as a spring, maintaining tension in bolted joints.

These washers are widely used in applications involving vibration, thermal expansion, and dynamic loads such as automotive assemblies, heavy machinery, pressure systems, and electrical equipment.
