Rotor Clip CG-250SJ External Spiral Retaining Ring

Product Description

The ROTOR CLIP CG-250SJ is an external spiral retaining ring designed to retain components on a 2.5-inch diameter shaft. The ring seats in a machined external groove and holds axial loads without the need for a separate fastener. Made from AISI 302 stainless steel with an oil finish, it offers solid corrosion resistance in wet or chemically exposed environments. The ring has a free diameter of 2.343 inches, a free outside diameter of 2.743 inches, and a groove diameter of 2.36 inches. Machinists, maintenance technicians, and mechanical assemblers install this type of ring in pumps, motors, gearboxes, and similar rotating equipment.

This retaining ring suits industrial and commercial applications where a reliable external groove retention method is required on 2.5-inch shafts. Typical installations include pump assemblies, conveyor drives, and motor shaft applications found in HVAC equipment, water treatment systems, and general mechanical machinery. The spiral design allows installation without special pliers in some configurations, though standard retaining ring tools are typically used for controlled assembly.

Compatibility

Designed for use on external shafts with a 2.5-inch shaft diameter and a machined groove diameter of 2.36 inches. Confirm groove width and groove depth dimensions against application requirements before installation.

Installation Notes

Installation should be performed by a qualified machinist or mechanical technician familiar with retaining ring assembly. Verify the shaft groove dimensions match the specified groove width, groove depth, and groove diameter tolerances before installing the ring. De-energize and lock out all equipment before working on rotating shaft components. Use appropriate retaining ring installation tools to avoid deforming the ring or damaging the groove surface.
