Wave washers, also commonly referred to as wave
springs or coiled wave springs, are used to absorb stress due to axial
compressive loads, acting as a cushion. The waves of the wave washer
provide 3, 4, or 6-point contact that results in greater load bearing capacity
and a medium range of deflection. Wave Springs or Washers are
specified for applications where a uniform force is required on a
circumference. The design of wave springs delivers higher load ratings in
confined spaces than standard compression springs.
Common applications for Wave Springs include valves, pumps, seals,
bearings, electrical switches and connectors etc.
