Rotor Clip CG-425SJ External Spiral Retaining Ring

Product Description

The ROTOR CLIP CG-425SJ is an external spiral retaining ring designed to retain components on a shaft without requiring a groove in the housing. It seats in a machined groove on the shaft outer diameter and resists axial displacement of assembled parts. The ring is manufactured from AISI 302 stainless steel with an oil finish, offering corrosion resistance suitable for demanding industrial environments. With a shaft diameter of 4.5 inches and a groove diameter of 4.065 inches, the CG-425SJ is sized for large-diameter shaft assemblies. Licensed machinists, millwrights, and mechanical maintenance technicians are the typical installers.

This external spiral retaining ring is suited for use in industrial rotating equipment, pump assemblies, gear drives, and heavy mechanical systems where a large-shaft external retention solution is required. Its spiral design allows installation without special snap-ring pliers in many configurations, and the stainless steel construction makes it appropriate for wet, corrosive, or washdown service conditions. It is sold individually with a minimum order quantity of one unit.

Compatibility

Designed as an OEM-style external spiral retaining ring for 4.5-inch diameter shafts with a machined groove meeting the specified groove diameter, width, and depth dimensions listed in the technical specifications.

Installation Notes

Installation must be performed by a qualified mechanic or millwright following applicable machinery safety procedures. De-energize and lockout-tagout all equipment before servicing shaft assemblies. Verify the shaft groove dimensions match the specified groove diameter, width, and depth before installing the ring to ensure proper seating and retention. Do not reuse a ring that has been removed, as the spiral geometry may be compromised.
