Rotor Clip SH-81ST Pa B100 External Snap Ring 13/16 in

Product Description

The ROTOR CLIP SH-81ST PA B100 is an external snap retaining ring designed to secure components on shafts in mechanical assemblies. It fits a 13/16 inch (0.8125 inch) shaft diameter and seats in a groove with a 0.762 inch groove diameter. The ring is manufactured from SAE 1060-1090 spring steel with a phosphate finish that provides basic corrosion resistance and lubricity. Hardness is rated at 66-71 HRC, giving the ring the spring tension required to hold its seated position under load. This part is sold in a minimum order quantity of 100 pieces and is appropriate for use by mechanical assemblers, maintenance technicians, and industrial tradespeople working on rotating shaft assemblies.

External snap retaining rings of this type are used wherever a removable, positive stop is needed on the outside of a shaft. Common applications include motors, gearboxes, pumps, and conveyor equipment where axial retention of bearings, gears, or other shaft-mounted components is required. The phosphate finish makes this ring suitable for general industrial environments. This ring conforms to SAE 1060-1090 and UNS G10600-G10900 material standards and is certified under ISO 13485:2015.

Installation Notes

External snap rings require snap ring pliers sized for external rings. Always power down and de-energize equipment fully before disassembling shaft assemblies. Confirm groove dimensions match the ring specifications before installation to avoid improper seating or ring ejection under load. Refer to applicable machinery safety standards and manufacturer service documentation when performing shaft-component service.
