Rotor Clip CG-150SJ External Spiral Retaining Ring

Product Description

The ROTOR CLIP CG-150SJ is an external spiral retaining ring designed to secure components on a 1-1/2 inch diameter shaft. Manufactured from AISI 302 stainless steel with an AMS-5866 and ISO 13485:2016 compliant material spec, this ring provides reliable axial retention without requiring a groove machined all the way around a traditional snap ring groove profile. The ring seats in an external groove with a 1.406 inch groove diameter and a groove width of 0.056 inches. At 0.050 inches thick and weighing approximately 0.008 pounds, it is suited for applications where weight and space are critical constraints. Installation and removal are tool-assisted without requiring special snap ring pliers due to the spiral winding design.

This retaining ring is used in light-to-medium duty shaft assemblies across industrial, medical device, and mechanical equipment applications. Its stainless steel construction makes it appropriate for environments where corrosion resistance is required, such as food processing equipment, fluid handling systems, pumps, and medical instruments. The spiral ring style allows for axial installation, which can simplify assembly on shafts where traditional snap ring plier access is restricted. Professionals in mechanical assembly, maintenance, and precision manufacturing commonly install this component.

Compatibility

Designed as an OEM-style external spiral retaining ring for 1-1/2 inch shafts with a groove diameter of 1.406 inches, groove width of 0.056 inches, and groove depth of 0.047 inches. Consult shaft and housing drawings to confirm groove tolerances before installation.

Installation Notes

Installation is performed by mechanical assembly technicians or maintenance professionals. Power down and de-energize all equipment before servicing any shaft assembly containing this ring. The spiral design allows axial installation by hand or with a flat pusher tool — avoid using sharp instruments that may scratch or deform the ring. Verify groove dimensions against the specified tolerances before seating the ring to ensure proper retention force.
