Wave spring
Smalley

An interlaced wave spring is formed from two constituent wave springs of similar thickness, amplitude and frequency. The two constituent wave springs are combined together by interlacing them so that the spring turns of each spring abut each other for substantially the entire length of the interlaced spring.

This interlacing effectively increases the thickness of the spring turns of the interlaced spring to thereby provide increased loading and greater fatigue resistance characteristics.

Interlaced Wave Springs are available as a special from Smalley. Smalley engineers are available to assist with spring design.
