Built from SAE 1060-1090 spring steel and finished with a phosphate coating, this ring is engineered for consistent snap engagement and corrosion resistance in demanding mechanical assemblies. It fits a 9\/32 inch (0.2813 inch) shaft diameter and seats in a groove measuring 0.261 inches in diameter. Hardness runs 69.5 to 73 HRC, giving the ring the spring-back and retention force required in rotating or static shaft applications. Machinists, maintenance technicians, and assembly professionals install this ring using standard snap ring pliers.\u003c\/p\u003e\n\u003cp\u003eThis retaining ring is suited for use in light-duty mechanical assemblies across HVAC equipment, pumps, motors, and general industrial components wherever a 9\/32 inch shaft external groove is present. Its compact free outside diameter of 0.49 inches makes it appropriate for assemblies with limited radial clearance. It is commonly found in blower motor shaft assemblies, pump impeller retention, and small gearbox applications. The phosphate finish provides a base layer of corrosion resistance and aids in lubrication retention during service.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal snap ring design seats in a shaft groove for reliable axial retention without additional hardware\u003c\/li\u003e\n  \u003cli\u003eSAE 1060-1090 spring steel construction with hardness of 69.5 to 73 HRC for consistent snap engagement\u003c\/li\u003e\n  \u003cli\u003ePhosphate finish provides corrosion resistance and lubrication retention\u003c\/li\u003e\n  \u003cli\u003eGroove diameter of 0.261 inches with tight tolerance of plus or minus 0.002 inches\u003c\/li\u003e\n  \u003cli\u003eRing thickness of 0.025 inches with tolerance of plus or minus 0.002 inches for precise groove fit\u003c\/li\u003e\n  \u003cli\u003eMeets SAE 1060-1090, UNS G10600-G10900, and ISO 13485:2015 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on 9\/32 inch (0.2813 inch) diameter shafts with an external groove diameter of 0.261 inches and groove width of 0.029 inches.

Ensure the shaft groove is clean and free of burrs before seating the ring to avoid deforming the ring or reducing retention force. Always power down and de-energize any equipment before servicing internal assemblies. Do not reuse a ring that has been over-expanded or shows signs of deformation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 9\/32 inches (0.2813 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 0.261 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: -0.002 to +0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.029 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width Tolerance\u003c\/strong\u003e: 0.000 to +0.003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Depth\u003c\/strong\u003e: 0.010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Diameter\u003c\/strong\u003e: 0.256 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Diameter Tolerance\u003c\/strong\u003e: -0.005 to +0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 0.49 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Thickness\u003c\/strong\u003e: 0.025 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Thickness Tolerance\u003c\/strong\u003e: -0.002 to +0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: SAE 1060-1090 Spring Steel (UNS G10600-G10900)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 1060\/1090\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 69.5-73 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Phosphate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE 1060-1090; UNS G10600-G10900; ISO 13485:2015\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.00024 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ROTOR CLIP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SH-28ST PA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51700016480562,"sku":"SH-28ST PA","price":1449.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9f13d9c3ae12142323ed0ce18cf77fd.jpg?v=1788384996","url":"https:\/\/voomisupply.com\/products\/rotor-clip-sh-28st-pa-snap-retaining-ring-9-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
