Retaining rings, also referred to as snap rings, primarily provide shoulders to locate or retain parts on shafts or in cylinders.

PAC retaining rings are produced at several of our locations in North America. Specialized equipment, much of our own design, contributes to maximum efficiency and cost-effective manufacturing.

Our skilled operators produce hundreds of millions of coiled retaining rings a year on modern equipment. Our product capability covers parts with inner diameters ranging from 1.57mm to 1830mm (.062" to 72.0").

Coiled retaining rings have obvious cost advantages over stamped rings: they avoid the tremendous amount of blanked scrap that stamped rings produce, and require neither expensive tooling or dies nor costly hardening processes.

We can manufacture rings with a number of gap configurations to assist with assembly, disassembly, and identification. In addition, we can provide ground surfaces and a variety of notches or holes at the ring gap.
