Rotor Clip – Retaining Rings

Rotor Clip manufactures a full line of inch, DIN, ANSI metric and JIS retaining rings to world standards, as well as a complete line of constant section rings, spiral retaining rings, and wave springs. There are over 50 different styles and over 1000 part numbers to fit virtually every application.

Retaining rings are metal fasteners that are installed into a groove on a shaft or in a housing or bore creating a shoulder that retains an assembly. They eliminate threading, tapping, drilling and other machining operations associated with more traditional fasteners like screws, nuts, bolts, cotter pins, washers and more.

They can significantly reduce production costs since the grooves can be machined with other production processes. Overall they provide a more compact, functional design than their traditional counterparts.


Retaining Rings

Tapered Section – Axially Installed

Tapered retaining rings have a tapered-section. When you compress the lugs to install the ring in a housing (or expand them to install over a shaft), the height of the ring decreases symmetrically from the top to the free ends. This construction makes it possible for the rings to exhibit a circular shape when released in the groove, which allows the ring to grip the bottom of the groove tightly along the ring’s entire edge. This feature provides high thrust load capacity.

Tapered Section – Radially Installed
Self-Locking and Push-On
Constant Section

Constant section retaining rings feature a uniform, constant section. This means that the material used to make the ring is the same width at any point along the circumference of the ring. These cost less than tapered and spiral retaining rings and provide only three point contact with the groove as shown below.

Spiral

Spiral retaining rings can either be single or multi-turn, depending on the application requirements. Multi-turn, spiral-wound retaining rings consist of two or more turns of in-house rolled flat wire material with rounded edges. The material is coiled on edge to provide a gapless ring with 360 degrees of retention. Spiral rings offer space savings in a radial direction since there are no assembly lugs as with tapered retaining rings.
