Rotor Clip CG-212SJ External Spiral Retaining Ring

Product Description

The ROTOR CLIP CG-212SJ is an external spiral retaining ring designed to seat in a machined groove on a shaft and retain components against axial movement. Built from AISI 302 stainless steel with an AMS-5866 designation, it is suited for applications where corrosion resistance and moderate spring tension are required. The ring fits a 2-1/8 inches shaft diameter with a groove diameter of 2.003 inches and a ring thickness of 0.078 inches. It is installed and removed by maintenance technicians, mechanical assemblers, and field service professionals working on rotating or sliding shaft assemblies.

This retaining ring is used in industrial, commercial, and light mechanical assembly applications where a reliable, groove-seated external fastener is needed on shafts in the 2-1/8 inch diameter class. Typical install scenarios include pump shafts, gearbox assemblies, conveyor components, and similar rotating equipment where bearing or component retention is required. The 302 stainless steel construction makes it appropriate for wet or mildly corrosive environments.

Installation Notes

Installation is typically performed by a qualified mechanical technician or assembler. De-energize and lock out all power sources before servicing any assembly containing this ring. Use appropriate spiral ring pliers or installation tools to avoid deforming the ring during seating. Verify groove dimensions and tolerances match the CG-212SJ specifications before installation to ensure proper retention.
