Belleville Washers

Belleville washers from Mubea meet the most stringent requirements for fatigue strength and against setting loss. Our disc springs are produced according to DIN 2093 specifications and are resistant to corrosion, features low-high temperature operation and antimagnetic properties.

Disc Spring Theory

Belleville Washer TheoryBelleville washers (also known as disc springs) are shallow conical rings that are subjected to axial loads. Normally, the ring thickness is constant and the applied load is evenly distributed over the upper inside and lower outside edges. Disc springs are generally manufactured from spring steel and can be subjected to static loads, rarely alternating loads, and dynamic loads. Disc springs can meet the most stringent fatigue life and set loss requirements. 

Belleville Washer Features:

  • High fatigue life
  • Different assemblies can be designed to achieve the desired load characteristics
  • Special materials and various surface coatings available
  • Better space utilization when compared to other spring types
  • Low creep tendency with the correct dimensioning
  • High load capacity with a small spring deflection

Mubea Disc Springs are used in a variety of applications which have included safety valves, safety brakes for lifts and elevators, couplings, aerial cable cars, machine tool clamping components, boiler suspension systems in power stations, backlash compensation for ball bearings, brakes for construction and railway vehicles, overload protection in electric transformers and many more.
