Wave Springs

Smalley, Lake Zurich, IL, announced a Nested Spirawave Wave Springs series. The multiple-turn, flat wire wave springs are coiled in parallel to produce two to three times as much force as traditional single-turn wave springs. They can be used to replace stacks of single-turn springs, eliminating misalignment and inconsistent loading. The tangle-resistant design allows for automated handling through the use of a single spring and a simplified assembly process. The springs are available from .500 to 4” or 16 to 3,000 mm in carbon and stainless steel.
