Rotor Clip CG-275SJ External Spiral Retaining Ring

Product Description

The ROTOR CLIP CG-275SJ is an external spiral retaining ring designed to seat in a machined groove on the outside diameter of a shaft, securing components axially without requiring a snap-ring pliers groove engagement. Manufactured from AISI 302 stainless steel to AMS-5866 and ISO 13485:2016 standards, this ring is built for applications where corrosion resistance and dimensional consistency are critical. The shaft diameter is 2.75 inches, the groove diameter is 2.602 inches, and the ring thickness is 0.093 inches. Maintenance machinists, MRO technicians, and OEM assembly teams typically install this style of retaining ring in rotating equipment and mechanical assemblies.

This ring is suited for use in industrial machinery, fluid handling equipment, and precision mechanical assemblies where a shaft diameter of 2.75 inches is present. The spiral design allows installation and removal by rotating the ring along the shaft groove rather than radially expanding it, making it a practical choice in tight-clearance assemblies or where standard snap rings are not feasible. The oil finish provides light corrosion protection during storage and handling prior to installation.

Compatibility

Designed as an OEM-style external spiral retaining ring for shafts with a 2.75 inch diameter and a machined groove conforming to the specified groove diameter, width, and depth dimensions listed in the technical specifications.

Installation Notes

Installation and removal of spiral retaining rings is typically performed by maintenance technicians or mechanical assemblers using the manufacturer-recommended spiral ring insertion tool. De-energize and lock out all rotating equipment before servicing any shaft-mounted components. Verify groove dimensions match the specified tolerances before seating the ring to ensure proper retention. Do not attempt to install this ring on shafts or in grooves that fall outside the stated dimensional tolerances.
