InterShim™ Wave Spring

The InterShim™ Wave Spring is engineered for reliable performance in demanding applications. Featuring alternating inactive (flat) and active (waved) turns, this patented design withstands torsional loads and high acceleration, ensuring precise and reliable performance when rotational movement is present.

Benefits:

• Engineered to withstand torsional loads and high acceleration.

• Increased efficiency by eliminating the need for multiple elements within the assembly line.

• Floating ends and floating bent ends can help prevent damage to the mating surface.

• Allows for higher preload or softer spring rates.

• Highly customizable in number of waves, turns, arrangement of shims/troughs, and materials.

How It Works:

• Design of the turns changes from inactive (flat) to active (waved) in alternation, with an inactive turn always followed by an active turn.

• Every inactive turn in between active turns act like a shim washer between 2 spring elements, preventing the wave trough of a higher-level active turn from moving onto the wave crest of a lower-level active turn due to displacement or circumferential movement caused by torsional loads.

• The turns of the wave spring, arranged with flat or waved shapes, are engineered to smoothly glide against each other. This design prevents the wave spring from collapsing, even when subjected to torsional loads that create relative movement between the active (waved) turns.

• Torsional resistance enhanced by inactive turns between layers.
