PRODUCT SHOWCASE: Large Retaining Rings and Wave Springs for Wind Energy


Smalley Steel Ring Company is a leading manufacturer of Spirolox® retaining rings and wave springs for the power generation industry. What makes Smalley different is that they coil the ring or spring in place of stamping it, meaning no tooling is required for manufacturing.

Spirolox retaining rings have No Ears to Interfere® with mating components in an application and are compatible with standard snap ring grooves. They have no gap or lugs allowing for tight radial applications.

Smalley wave springs reduce operating height by up to 50 percent with the same force and deflection as coil springs, allowing them to fit in applications other springs cannot. Wave Springs are manufactured to satisfy precise operating conditions, including the tight radial and axial spaces, found in many applications.

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 two weeks. Over 10,000 parts are available from stock, 1/4” to 16”, in both carbon and stainless steel. Ask a Smalley engineer about this new series.

Smalley prides itself on its commitment to the highest quality and performance standards. Each retaining ring and wave spring is engineered with their No-Tooling-Charge™ process allowing for endless possibilities in dimension and material to suit your application needs.

Having worked with wind turbine designers, Smalley Engineers are available to assist with application specific retaining ring and wave spring design. Contact a Smalley engineer today with your design requirements.

Free CAD downloads and part samples are available to facilitate fast and efficient prototyping.
