The ROTOR CLIP CG-425ST OIL is an external spiral retaining ring designed for use on 4.5-inch diameter shafts. It seats in a machined external groove and provides a removable shoulder to retain components on a shaft without requiring secondary fasteners or threading. Manufactured from SAE 1060-1090 steel (UNS G10600-G10900) with an oil finish coating for corrosion resistance during storage and assembly, this ring has a groove diameter of 4.065 inches, a ring thickness of 0.111 inches, and a groove width of 0.12 inches. It is installed by licensed mechanical technicians and machinists in industrial, OEM, and MRO applications.
This ring is suited for medium-to-large shaft assemblies in industrial equipment, power transmission systems, pumps, motors, and gearboxes where a reliable external groove retainer is required. The spiral ring design allows tool-free or low-effort radial installation without special pliers in many configurations, making it practical for production-line and field-service environments. It conforms to SAE 1060-1090 and UNS G10600-G10900 fastener standards and meets ISO 13485:2015 quality management standards.
Designed for external groove installation on 4.5-inch diameter shafts with a groove diameter of 4.065 inches and groove width of 0.12 inches machined to SAE spiral ring groove specifications.
Installation is performed by qualified mechanical technicians or machinists. Verify shaft groove dimensions match the ring specifications before installation. Ensure the shaft and surrounding assembly are de-energized and secured before servicing. Spiral retaining rings are installed radially into the groove and should be fully seated around the entire groove circumference before the assembly is returned to service.
