Belleville Washers As Per DIN 137 B

Introduction of DISC SPRINGS AS PER DIN 2093 :

Disc Springs are conically formed annular discs, which are loaded in the axial direction. Disc Springs offer a well-developed solution to many engineering problems through a unique combination of high force in a small space. Disc Springs can be used as single disc or arranged in stacks. A spring stack can consists of either single springs or parallel spring sets. Disc Springs are available with or without contact flats. Disc Springs confirm to DIN 2093. Heavy series Disc Springs are manufactured from forgings. We have computerized design program to assist our customers for their specific applications. Disc Springs are mainly manufactured from Spring Steel material.

Our Disc Springs are AUSTEMPERED. This method of heat treatment is particularly effective for springs, as it gives the maximum toughness and therefore considerable durability.

ADVANTAGES OF DISC SPRINGS AS PER DIN 2093

  • No Deformation of Fatigue under normal loads.
  • High Energy Storage Capacity.
  • Long Service Life.
  • Stock keeping is minimized as the individual spring sizes can be combined universally.
  • Space saving.
  • Largely Self-damping, giving good shock absorption and energy dissipation.
  • Efficient use of space and high spring force with small deflections.
  • Adaptable to stacking in numerous configurations, Thus having modular spring element.
  • Low cost & Greater Security.

Material :

Spring Steel, Stainless Steel and 17 - 7 PH. Other Special material are available on request.
