Rotor Clip SH-43ST Pa B100 External Snap Ring 7/16 in

Product Description

The ROTOR CLIP SH-43ST PA B100 is an external snap retaining ring designed to secure components onto shafts in a wide range of mechanical and industrial assemblies. Manufactured from SAE 1060-1090 spring steel with a phosphate finish, this ring fits a 7/16 inch (0.4375 inch) shaft diameter and seats into a groove measuring 0.412 inches in diameter and 0.029 inches wide. The ring measures 0.025 inches thick and carries a hardness rating of 69.5 to 73 HRC, providing reliable retention under axial load. Maintenance technicians, millwrights, and mechanical assemblers install this type of ring during equipment assembly or service.

This external snap ring is suited for use in rotating shaft assemblies, gearboxes, motors, pumps, and general mechanical drive components where positive axial retention is required on a 7/16 inch shaft. The phosphate finish provides a base level of corrosion resistance and aids in lubrication retention. This part ships in a minimum order quantity of 100 units per package, making it appropriate for production-line use, MRO stocking, or fleet maintenance operations where volume consumption is expected.

Compatibility

Designed as an OEM-style external snap retaining ring for mechanical shaft assemblies requiring a 7/16 inch shaft diameter and a 0.412 inch groove diameter. Verify groove width, groove depth, and shaft diameter tolerances against your application before installation.

Installation Notes

Install and remove external snap rings using snap ring pliers sized for external rings to avoid deforming the ring or damaging the groove. Power down and de-energize all equipment before servicing any shaft assembly. Confirm the groove is clean and free of burrs before seating the ring. Do not reuse snap rings that have been deformed, nicked, or overstressed during removal.
