Belleville Washers

Belleville washers are conical-shaped disc springs used to apply consistent loads and manage stress in mechanical assemblies. Their design enhances system reliability by compensating for dimensional variations and thermal expansion.

Common Applications

aerospace components

automotive assemblies

machinery vibration control

electrical connections

load cushioning devices

thermal expansion compensators

Buying Guide

Belleville Washers Buying Considerations

  • Assess the load capacity requirements to choose the correct washer thickness and material.
  • Consider environmental conditions like temperature and humidity that the washers will endure.
  • Evaluate the need for corrosion resistance based on application settings.
  • Think about the possibility of stacking washers to achieve desired load characteristics.
  • Verify compatibility with other fasteners and hardware used in your assembly.
