Rotor Clip SH-175ST Pa External Snap Retaining Ring

Product Description

The ROTOR CLIP SH-175ST PA is an external snap retaining ring designed to secure components on shafts in industrial and mechanical assemblies. Sized for a 1-3/4 inch shaft diameter with a groove diameter of 1.65 inches, this ring seats firmly into a machined groove to prevent axial movement of bearings, gears, pulleys, and similar components. Manufactured from SAE 1060-1090 spring steel with a phosphate finish, it delivers a hardness range of 47-52 HRC for reliable retention under load. The ring measures 0.062 inches thick and 0.068 inches in groove width. Machinists, millwrights, and maintenance technicians install these rings across a wide range of rotating equipment and drive-train applications.

This external retaining ring is suited for use in motors, pumps, gearboxes, compressors, and general industrial machinery where shaft retention is required. The 1-3/4 inch shaft size is common in commercial HVAC equipment, industrial fan assemblies, and power transmission components. The phosphate finish provides a degree of corrosion resistance and improved lubrication retention during assembly. The ring is sold individually with a minimum order quantity of 10 units, making it appropriate for service shops and production environments that maintain standard fastener stock.

Installation Notes

External snap retaining rings of this type are installed using external snap ring pliers sized for the ring diameter. The shaft groove must be clean, within tolerance, and free of burrs before installation. Wear appropriate eye protection, as snap rings can release under spring tension during installation or removal. Verify groove dimensions against the ring specifications before installation to ensure proper seating and retention.
