Rotor Clip CG-225SJ External Spiral Retaining Ring

Product Description

The ROTOR CLIP CG-225SJ is an external spiral retaining ring designed to secure components on a 2.25-inch shaft using a machined groove. The ring seats into a groove with a 2.12-inch diameter and a width of 0.086 inches, holding axial position without the need for threaded fasteners or welding. Manufactured from AISI 302 stainless steel to AMS-5866 and ISO 13485:2016 standards, this ring delivers corrosion resistance suitable for demanding industrial and mechanical applications. Maintenance technicians, mechanical assemblers, and field service professionals working on rotating shafts, pumps, gearboxes, and similar assemblies install this ring type as a lightweight, low-profile retention solution.

This external spiral retaining ring is intended for use on shafts with a 2.25-inch diameter where a spiral-wound ring style is specified. The spiral design allows installation and removal with standard retaining ring pliers without requiring a dedicated housing bore. Typical applications include pump shafts, motor shafts, conveyor assemblies, and industrial equipment requiring a reusable, corrosion-resistant axial fastener. The 302 stainless steel construction makes this ring well suited for wet, washdown, or mildly corrosive environments where carbon steel rings would be inappropriate.

Compatibility

Designed as an OEM-style external spiral retaining ring for shafts with a 2.25-inch diameter and a groove diameter of 2.12 inches machined to specifications consistent with AISI 302 and AMS-5866 standards.

Installation Notes

Installation is performed by mechanical assemblers or maintenance technicians using spiral retaining ring pliers appropriate for the ring diameter. Before installation, verify the shaft groove dimensions match the specified groove diameter, width, and depth tolerances to ensure proper seating and retention force. Clean the groove of debris or burrs before inserting the ring. Never force or over-compress a spiral ring beyond its designed flex range, as distortion will reduce retention capacity.
