WHAT ARE RETAINING RINGS?

Trends in recent years have been away from threaded fasteners and in favor of retaining rings. 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.

ADVANTAGES OVER TRADITIONAL FASTENERS

Less shaft/housing preparation (threading, tapping, drilling, etc.)
Reduced weight and size of finished design
LOWER COSTS of raw material and labor
