Rotor Clip SH-56ST Pa B100 External Snap Ring 9/16 in

Product Description

The ROTOR CLIP SH-56ST PA B100 is an external snap retaining ring designed to secure components onto shafts in mechanical assemblies. It seats in a machined groove on the outer diameter of a shaft and prevents axial movement of mounted parts. Made from SAE 1060-1090 spring steel with a phosphate finish, this ring delivers reliable retention strength and corrosion resistance in a compact profile. Hardness is rated at 66 to 71 HRC, making it suitable for high-stress fastening applications. Licensed trades and maintenance technicians working on industrial, HVAC, or mechanical drive assemblies will encounter this ring as a standard retention component. It is sold in a minimum order quantity of 100 pieces.

This external snap ring fits a 9/16 inch (0.5625 inch decimal) shaft diameter with a groove diameter of 0.530 inches. It is used in a wide range of rotating and stationary shaft applications including motor assemblies, gearboxes, pump shafts, and similar mechanical equipment where positive axial retention of a bearing, collar, or hub is required. The phosphate finish provides a base suitable for light corrosion protection in moderate service environments. Installation requires only snap ring pliers rated for external rings of this size class.

Installation Notes

Installation and removal of external snap rings requires external snap ring pliers matched to the ring ear openings — never use screwdrivers or picks, as they can distort the ring or cause it to eject at high velocity. De-energize and lock out all rotating equipment before servicing any shaft assembly. Verify the shaft groove dimensions match the ring specifications before installation to ensure full seating and rated retention. Handle spring steel rings with care as sharp edges can cause lacerations.
