The Parts You Need to Build

Rings can be manufactured in sizes from  .001″ to 40″ (1mm to 1200mm) meeting inch, DIN, ANSI and JIS standards. Many materials and finishes are available to suit one’s requirements, and Rotor Clip’s knowledgeable sales engineers are available to assist designers in selecting which options are best for their project.

For spiral retaining rings, spring steel (SAE 1070-1090) and AISI 302 stainless steel materials are usually requested for the aerospace industry. 17-7PH Cond. CH900 is the preferred stainless steel for wave springs. Both stainless parts are often passivated to AMS2700.

For military applications, cadmium plating of carbon steel is often requested, as well as Black Oxide for camouflage. Rotor Clip offer retaining rings certified to military standards in the popular materials and finishes listed below.
