Rotor Clip CG-300SJ External Spiral Retaining Ring 3 in

Product Description

The ROTOR CLIP CG-300SJ is an external spiral retaining ring designed to seat in a machined groove on a 3-inch diameter shaft. Spiral retaining rings install without special pliers — they wind into the groove under axial load — making them a practical choice when access is limited. This ring is manufactured from AISI 302 stainless steel per AMS-5866, with an oil finish applied at the factory. The groove diameter is 2.838 inches, ring thickness is 0.093 inches, and the free outside diameter is 3.268 inches. Mechanical assemblers, maintenance technicians, and OEM production teams are the primary users.

This retaining ring is suited for industrial shaft assemblies requiring a corrosion-resistant fastener in environments where carbon steel rings would degrade. Typical applications include pump shafts, gearboxes, motors, and rotating assemblies in wet or chemically exposed settings. The 302 stainless material and oil finish make it appropriate for moderate-corrosion environments. It is sold individually and is intended for direct OEM replacement or new assembly builds where a 3-inch shaft groove specification is required.

Installation Notes

Installation is performed by mechanical technicians or assemblers familiar with retaining ring fasteners. Power down and de-energize any rotating equipment before servicing shaft assemblies. Spiral retaining rings are wound into the groove axially; inspect the groove for burrs or damage before seating the ring. Verify groove tolerances match the ring specifications to ensure proper retention under load.
