Wave Springs and Retaining Rings for medical applications

Our Smalley Spirolox Retaining Rings and Wave Springs are suitable for a range of medical devices, including surgical instruments, implantable devices, imaging equipment and dental tools.

For almost 40 years, TFC has partnered with US-based Smalley Steel Ring Company to become the leading European supplier and technical support centre for Smalley™s Wave Springs, Spirolox Retaining Rings and Snap Rings. Smalley is ISO 13485:2016 certified, a Quality Systems Standard written specifically for medical device manufacturers.

The flagship Crest-to-Crest® multi-turn compression springs have always been of interest to designers because of their axial and radial space-saving features. As engineers around the world design smaller assemblies, the question is, where can they find the compact components to support their designs?

Over the past decade, Smalley™s production team has enhanced its ability to produce smaller springs to match the requirements of the medical and electronic industries. This has culminated in the expansion of the popular YC and YCM series down to 0.188 inches and 5 mm in diameter. Special designs are also available down to 0.157 inches or 4mm in diameter.

Smalley™s unique edge-winding process enables parts to be cost-effectively manufactured from many materials, including surgical 316 stainless steel and implantable titanium.

Smalley Wave Springs reliably satisfy precise operating conditions, which make them ideal for the tight radial and axial spaces found in many medical applications. The latest developments from Smalley have created further possibilities for designers in the medical industry, where typically small cavity sizes limit the available spring force properties.
