Rotor Clip CG-237SJ External Spiral Retaining Ring

Product Description

The ROTOR CLIP CG-237SJ is an external spiral retaining ring designed to secure components on shafts in mechanical assemblies. It seats in a precision-cut external groove on a 2-3/8 inch shaft, holding the ring at a groove diameter of 2.239 inches. Manufactured from AISI 302 stainless steel with an oil finish, this ring resists corrosion in demanding service environments. Ring thickness measures 0.078 inches and groove width is 0.086 inches. Machinists, millwrights, and maintenance technicians install this type of ring wherever axial retention of bearings, gears, or other shaft-mounted components is required without threading or welding.

This retaining ring is suited for use in industrial machinery, pump assemblies, electric motor shafts, and other rotating equipment requiring positive axial retention on a 2-3/8 inch shaft. The spiral design allows installation and removal with standard retaining ring pliers, making it practical for field service and production line assembly alike. Its stainless steel construction makes it a common selection for food processing, marine, and other corrosive-environment applications where carbon steel rings are not appropriate.

Compatibility

Designed for external groove retention on shafts with a 2-3/8 inch nominal diameter. Confirm groove width, groove depth, and groove diameter tolerances match application requirements before installation.

Installation Notes

Installation and removal should be performed by qualified mechanical technicians using retaining ring pliers sized for this ring diameter. De-energize and lock out all rotating machinery before servicing shaft-mounted components. Inspect the shaft groove for burrs or damage prior to seating the ring. Do not over-spread the ring during installation, as spiral retaining rings can deform if forced beyond their rated flex range.
