Smalley® Wave Springs

Circular-Grain™ Shims

Smalley Circular-Grain™ shims are commonly used in conjunction with wave springs where a backup plate is needed for housings made of softer metals like aluminum or bronze, and for packings made of leather, neoprene or similar materials. Shims can function as spacers to change wave spring operating heights.

Adding or subtracting shims is an excellent method of adjusting load on a wave spring. Using a shim spacer can also control tolerance buildups.
