High Temperautre Spring Disc Spring Wave Spring

High Temperature Spring :

Spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force, and return to their original shape after removing the external force. Also used as "spring". Generally made of spring steel. The types of springs are complex and diverse.

  ♦♦♦ Wave Springs ♦♦♦

Wave spring is a thin ring-shaped elastic metal element composed of several wave crests and valleys. Wave springs are widely used in motors, textile machinery, hydraulic equipment, automobiles and other industries. The main installation and specifications (nominal size) of the bearing room are suitable. Or in the hole, the installation space is small, and it has the special function of reducing noise and reducing vibration.

The outer diameter ranges from 6mm to 1000mm.the thickness ranges from 0.4mm to 5.0mm.

Rust protection

  • Phosphating
  • Mechanical galvanizing
  • Nickel plated
  • Jiaomei

They have the characteristics of small deformation and large load. It also has the following features.

  • Disc springs can obtain different load characteristics through different combinations of inversion and overlap.
  • Compared with other springs, disc springs take up less space.
  • When multiple sheets are used in combination, the damping effect is increased.
  • When used reasonably, it will not deform or break.
  • Longer fatigue life.
