About Smalley

Smalley manufactures wave springs and retaining rings using a flat-wire edgewinding process. Its custom work can adapt an existing design or start from application requirements such as space, load, deflection and material. Engineering staff help review feasibility and manufacturability, while prototype parts allow customers to evaluate fit and function before production. The company rolls its own wire and describes a vertically integrated U.S. manufacturing operation. Smalley is headquartered in Lake Zurich, Illinois, with overseas offices and a wider distribution network; this profile focuses on its custom manufacturing services.
