Rotor Clip CG-375ST Oil External Spiral Retaining Ring

Product Description

The ROTOR CLIP CG-375ST OIL is an external spiral retaining ring designed to secure components on a 3-3/4 inch diameter shaft. Manufactured from SAE 1060-1090 steel and finished with an oil coating for corrosion resistance, this ring seats in a precision groove with a 3.552 inch groove diameter and a 0.12 inch groove width. The spiral design allows installation and removal without special pliers in many applications, making it a reliable choice for mechanical assemblies in industrial, HVAC, and rotating equipment maintenance. Machinists, millwrights, and mechanical technicians are the primary installers.

This retaining ring is suited for use in industrial machinery, rotating shaft assemblies, pump housings, fan hubs, gearboxes, and similar mechanical systems where a positive external stop is required on a 3-3/4 inch shaft. Its oil coating helps protect against light corrosion during storage and service in moderate environments. The ring is appropriate for both OEM assembly and field repair applications where maintaining precise axial positioning of bearings, gears, or other components is critical.

Installation Notes

Installation and removal should be performed by a qualified mechanic or millwright following standard retaining ring procedures. De-energize and lock out all rotating equipment before servicing any shaft assembly. Use appropriate spiral retaining ring pliers or tools rated for the ring diameter to prevent distortion of the ring or injury during installation. Verify groove dimensions conform to the specified tolerances before installation to ensure proper retention and prevent ring rollout under load.
