Smalley Steel Ring Company is a leading manufacturer of Spirolox Retaining Rings Constant Section Rings and Smalley Wave Springs for the power generation industry. What makes Smalley different is that we coil the ring or spring in place of stamping it, meaning no tooling is required for manufacturing. Smalley’s standard Wind Power Series is available in up to 120” diameters. Standard materials sizes are stocked for production, with delivery in as little as 2 weeks. Over 10,000 parts are available from stock, 1/4” to 16”, in both carbon and stainless steel.
