Rotor Clip CG-500ST Oil Spiral Retaining Ring 5 in

Product Description

The ROTOR CLIP CG-500ST OIL is an external spiral retaining ring designed to seat in a machined groove on a 5-inch diameter shaft, providing a positive stop that retains assembled components against axial movement. Manufactured from SAE 1060-1090 steel with an oil finish coating, this ring delivers solid performance in heavy-duty mechanical assemblies. The ring measures 0.111 inches thick and seats in a 0.120-inch wide groove at a groove diameter of 4.79 inches. Licensed machinists, millwrights, and mechanical assembly technicians typically install this type of retaining ring in industrial rotating equipment, gearboxes, and shaft-mounted assemblies.

This external spiral retaining ring is suited for large-shaft industrial applications where a conventional stamped ring or snap ring may not provide adequate load distribution across the groove. The spiral design allows installation and removal without special pliers in some configurations, though groove alignment and proper seating remain critical. This ring is appropriate for use on 5-inch shafts in equipment ranging from large electric motors and pump assemblies to gearbox output shafts and conveyor drive components where axial component retention is required.

Compatibility

Designed as an OEM-style external spiral retaining ring for shafts with a 5-inch nominal diameter and a machined groove conforming to the specified groove width, groove depth, and groove diameter dimensions listed in the technical specifications.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with retaining ring procedures. De-energize and lock out the machine before servicing any shaft-mounted components. Confirm groove dimensions match the ring specifications before installation, as an undersized or oversized groove can cause ring failure under load. Safety glasses are required during installation, as retaining rings can slip during seating and become a projectile hazard.
