Rotor Clip CG-250ST Oil Spiral Retaining Ring 2-1/2 in

Product Description

The ROTOR CLIP CG-250ST OIL is an external spiral retaining ring designed for 2-1/2 inch shaft diameters with a groove diameter of 2.36 inches. Manufactured from SAE 1060-1090 steel (UNS G10600-G10900) and finished with an oil coating for corrosion protection, this ring seats into a machined external groove to axially retain components on a shaft without the need for secondary fasteners. Ring thickness measures 0.078 inches and groove width is 0.086 inches. It is installed and removed by mechanical and industrial maintenance technicians working on rotating assemblies, conveyor systems, pumps, and similar equipment.

This retaining ring is suited for industrial and mechanical applications where an external groove on a shaft requires a reliable, low-profile axial stop. Typical installations include gearboxes, motor shafts, bearing retention assemblies, and rotating drive components. The spiral ring design allows installation without special snap-ring pliers in some configurations, though standard retaining ring tooling is commonly used. The oil finish is appropriate for environments where light corrosion resistance is needed during storage and service.

Compatibility

Designed as an OEM-style external spiral retaining ring for 2-1/2 inch shafts with a 2.36 inch groove diameter machined to standard tolerances.

Installation Notes

Installation is performed by qualified mechanical or industrial maintenance technicians. De-energize and lock out all power sources to the machine before servicing rotating assemblies. Use appropriate retaining ring installation and removal tools to seat the ring fully into the groove without distorting the ring geometry. Verify groove dimensions and tolerances match the ring specifications before installation.
