Rotor Clip CG-125SJ External Spiral Retaining Ring

Product Description

The ROTOR CLIP CG-125SJ is an external spiral retaining ring designed for 1-1/4 inch shaft diameters with a groove diameter of 1.176 inches. Manufactured from AISI 302 stainless steel and finished with an oil coating, this ring meets AMS-5866 and ISO 13485:2016 standards. The spiral design allows for installation without special assembly tools, making it a practical choice for maintenance and production environments where standard e-clips or stamped rings are not suitable. It is installed and serviced by mechanical assemblers, maintenance technicians, and industrial MRO professionals working on rotating shafts and assemblies.

This retaining ring is used in applications requiring a secure external axial shaft retention solution. The 302 stainless steel construction provides corrosion resistance for environments exposed to moisture, mild chemicals, or washdown conditions. Typical install scenarios include pump shafts, gearboxes, conveyor components, and other rotating machinery where a reliable external retaining feature is needed. The ring seats into a machined groove on the shaft OD and provides a positive stop against axial movement of mounted components.

Installation Notes

This retaining ring is installed by mechanical technicians and assemblers working on rotating shaft assemblies. De-energize and lock out all equipment before servicing any shaft or bearing assembly. Verify the shaft groove dimensions match the ring specifications before installation to ensure proper seating and retention. Spiral retaining rings are wound into the groove starting at one end — do not force or hammer the ring, as this can deform the ring or damage the groove.
