Manufactured from 15-7 Grade 632 stainless steel to AMS-5529 and UNS S15700 standards, this ring delivers high hardness in the 69.5 to 73 HRC range, making it suitable for demanding mechanical assemblies where wear resistance and dimensional stability matter. A zinc finish adds a layer of corrosion protection. It is installed into a precision-cut groove on the outside of a shaft and is used by mechanical assemblers, maintenance technicians, and industrial tradespeople working across rotating equipment and fastener-critical assemblies.\u003c\/p\u003e\u003cp\u003eThis ring fits applications requiring tight groove tolerances on small-diameter shafts. With a groove diameter of 0.261 inches and a groove width of 0.029 inches, it is suited for precision shaft assemblies in industrial machinery, instrumentation, and mechanical drive components. The free outside diameter of 0.49 inches and ring thickness of 0.025 inches allow it to seat securely in properly machined grooves. It meets ISO 13485:2015 standards, making it appropriate for controlled manufacturing environments where documented quality standards are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExternal retaining ring design for outside-diameter shaft groove installation\u003c\/li\u003e\n\u003cli\u003e15-7 Grade 632 stainless steel construction per AMS-5529 and UNS S15700\u003c\/li\u003e\n\u003cli\u003eHardness range of 69.5 to 73 HRC for high wear resistance\u003c\/li\u003e\n\u003cli\u003eZinc finish provides supplemental corrosion protection\u003c\/li\u003e\n\u003cli\u003eGroove diameter of 0.261 inches with a tolerance of -0.002 to +0.002 inches\u003c\/li\u003e\n\u003cli\u003eMeets ISO 13485:2015 quality standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on shafts with a 9\/32-inch (0.2813-inch) diameter requiring an external retaining ring groove machined to 0.261-inch groove diameter, 0.029-inch groove width, and 0.010-inch groove depth per standard external ring groove specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires external retaining ring pliers sized for small-diameter rings. The shaft groove must be machined to the specified dimensions before ring installation. Always relieve shaft load and power down rotating equipment before servicing retaining rings. Avoid over-spreading the ring during installation, as this can exceed the material elastic limit and compromise retention force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 9\/32 inch (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: 15-7 Grade 632 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: AMS-5529 \/ UNS S15700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 69.5 to 73 HRC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: AMS-5529, UNS S15700, ISO 13485:2015\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-28SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51722094084402,"sku":"SH-28SS","price":805.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bdd7e3d5f2af4164db9d9a73af6439b3_ded21e29-e9b9-4c85-9c1f-7b495ee0b99e.jpg?v=1788585578","url":"https:\/\/voomisupply.com\/products\/rotor-clip-sh-28ss-external-retaining-ring-9-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
