Smalley Wave Springs are an alternative to Belleville Springs. Wave springs are manufactured to specified dimensions. They arrive as ordered with a specific number of turns and configuration for precise and repeatable performance. The one-piece spring can be installed without the need to stack multiple springs together.
Alternatively, Belleville stacks are comprised of multiple washers stacked in various combinations. Often stacking Belleville’s requires trial-and-error to deliver the appropriate load. A single wave spring reduces the risk of error in assembly and delivers a predicable performance, minimizing load variances.
