Rotor Clip SH-237ST Pa External Snap Retaining Ring

Product Description

The ROTOR CLIP SH-237ST PA is an external snap retaining ring designed to secure components on shafts in industrial and mechanical assemblies. Machined to fit a 2.375-inch (2-3/8 inch) shaft diameter with a groove diameter of 2.239 inches, this ring seats firmly in the groove to prevent axial movement of bearings, gears, and similar components. Manufactured from SAE 1060-1090 spring steel (UNS G10600-G10900), it delivers a Rockwell hardness of 47-52 HRC for reliable retention under load. The phosphate finish provides baseline corrosion resistance suited to indoor industrial environments. Installed by maintenance technicians, millwrights, and mechanical assemblers across a wide range of rotating equipment applications.

This retaining ring is used in shaft assemblies where external groove retention is required. Typical applications include electric motor shafts, gearboxes, pump assemblies, conveyor drive shafts, and general industrial machinery. The inch-based dimensional system makes it a standard fit for equipment designed to SAE specifications. With a free outside diameter of 3.06 inches and a ring thickness of 0.078 inches, it is appropriate for medium-duty shaft assemblies requiring precise axial control at the 2-3/8-inch shaft size.

Compatibility

Designed as an OEM-style external snap retaining ring for shaft assemblies requiring a 2-3/8 inch shaft diameter and a 2.239 inch groove diameter per SAE inch-series retaining ring standards.

Installation Notes

Installation and removal require external snap ring pliers sized for this ring diameter. Power down and de-energize all equipment before servicing shaft assemblies. Ensure the groove is clean and free of debris before seating the ring, and confirm the ring is fully seated in the groove before returning the assembly to service. Do not over-stress the ring during installation by spreading it beyond its free outside diameter more than necessary.
