Brass Belleville Washers

Belleville washers are a more economical and less precise form of conical disc spring, best used for static applications where some setting and/or loss of force can be tolerated. Belleville washers, manufactured from steel strip, are not pre-stressed during the manufacturing process and the inside and outside diameters of the disc spring are not machined. The usual protective surface treatment is phosphate and oiled.

  • With suitable arrangement, a large damping (high hysteresis) effect may be achieved.
  • Because the springs are of an annular shape, force transmission is absolutely concentric.
