Smalley Datasheets for Preload Springs, Spacers, and Washers

Preload springs, spacers, and washers are meant to maintain tension in an assembly where some slack may be present. Their capabilities can eliminate rattle, compensate for expansion or contraction of the assembly materials, or absorb intermittent shock loads. These products are made of elastic deformable materials, most commonly convoluted ductile, high-strength metal alloys which come in machined, welded, and open-ring varieties.

Product Name Notes
Conventional Gap and Overlap Type Wave Springs are used in a wide variety of applications. For short deflections and low-medium forces, they function with precision and dependability. These two types...
Crest-to-Crest Wave Springs are pre-stacked in series, decreasing the spring rate proportionally to the number of turns. Uses are typically applications requiring low-medium spring rates and large deflections with low-medium...
Wavo Springs are produced from round-section wire to provide higher loads while maintaining the accurate loading found in wave springs. As an alternative to Belleville Springs, the Wavo provides similar...
