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.
