Nested Wave Springs

Nested Spirawave^(R) springs are flat wire wave springs with multiple turns, coiled in parallel to produce higher forces. These forces increase proportionally to the number of turns. Now available as a standard series, they are able to replace stacks of single-turn wave springs when applications require higher loads than single-turns are capable of producing.

Benefits of Nested Spirawave Springs

When your application requires high forces in tight radial or axial spaces, a nested wave spring is a perfect solution.

• Two to three times the force of a single-turn wave spring
• Replaces stacks of single-turn springs
  • Eliminates misalignment and uneven loading issues
  • Lowers costs
  • Quicker and simpler assembly times
• Sturdy and tangle-resistant design for automated handling
• Fast delivery on standard carbon and stainless parts from .500 – 4" or 16 – 100 mm
  • Thousands available from stock for next day shipping
  • Three weeks lead time on standard parts in non-stock quantities
• Custom parts from .118 – 120" (3 – 3000 mm) available in carbon, stainless, and exotic alloys

Applications

Heavy-Duty Bearing Preload

In very high load applications, a three-turn spring produces the high forces necessary for heavy duty bearing preload. Bearing preload is necessary in order to protect an assembly from noise and vibration.

Low Voltage Connector

A Bayonet Connector couples as the male end rotates and follows the groove contour in the female end. A 2-Turn Nested Spirawave Wave Spring provides the preload between the two halves. A 2-Turn Nested Spring was necessary to develop a higher load in a very tight radial and axial space.
