Nested Spirawave® 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.
When your application requires high forces in tight radial or axial spaces, a nested wave spring is a perfect solution.
Our engineers have been designing custom Nested Wave Springs for over 30 years, and they are ready for your challenge. Customs can be produced from .157 to 120" (4 to 3000 mm) in carbon steel, stainless steel, or exotic alloys, with many other variants. Fill out our custom wave spring checklist and contact a Smalley Engineer to get started.
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.
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.
