Designed for a 2-1\/2 inch shaft diameter with a 2.36 inch groove diameter, this ring seats firmly into machined grooves to prevent axial movement of components. Manufactured from SAE 1060-1090 spring steel with a phosphate finish, it delivers reliable corrosion resistance and hardness in the 47-52 HRC range. Licensed tradespeople, maintenance technicians, and mechanical assemblers install this type of fastener in rotating shaft assemblies across industrial, HVAC, and mechanical systems where positive component retention is required.\u003c\/p\u003e\n\u003cp\u003eThis external retaining ring is suited for use in shaft assemblies where space constraints and high-cycle performance demand a compact, reliable retention solution. It is installed in groove-machined shafts with a 2.36 inch groove diameter and is commonly found in pump assemblies, fan shaft applications, gearboxes, and other rotating mechanical equipment requiring secure axial load management. The phosphate finish makes it appropriate for environments where mild corrosion resistance is needed alongside mechanical durability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal snap ring design for axial retention on 2-1\/2 inch diameter shafts\u003c\/li\u003e\n  \u003cli\u003eSAE 1060-1090 spring steel construction with 47-52 HRC hardness for reliable spring-back and retention force\u003c\/li\u003e\n  \u003cli\u003ePhosphate finish provides mild corrosion protection and improved surface adhesion for lubricants\u003c\/li\u003e\n  \u003cli\u003eGroove width of 0.086 inches and groove depth of 0.07 inches for precise machined groove fitment\u003c\/li\u003e\n  \u003cli\u003eFree outside diameter of 3.17 inches allows for controlled installation and positive seating\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 as an OEM-style external snap retaining ring for shafts with a 2-1\/2 inch shaft diameter and a machined external groove meeting the specified groove diameter, width, and depth dimensions listed in the technical specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eExternal snap retaining rings of this type are installed and removed using snap ring pliers rated for external ring service — use the correct tip size to avoid ring distortion or eye hazard from sudden release. De-energize and lock out all equipment before servicing any shaft assembly. Inspect the groove for wear or burrs before seating the ring; a damaged groove can compromise retention force. Follow applicable ANSI and OSHA lockout\/tagout procedures when working on rotating machinery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Type\u003c\/strong\u003e: External Snap Retaining Ring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 2.36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: -0.006 to 0.006 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Diameter\u003c\/strong\u003e: 2.313 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 3.17 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.086 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Depth\u003c\/strong\u003e: 0.07 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Thickness\u003c\/strong\u003e: 0.078 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Thickness Tolerance\u003c\/strong\u003e: -0.003 to 0.003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Spring Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: SAE 1060-1090 \/ UNS G10600-G10900\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 47-52 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\u003eWeight\u003c\/strong\u003e: 0.0297 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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-250ST PA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51698926682418,"sku":"SH-250ST PA","price":1302.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d16da90b9e1e0a7c2cd70635048b1d11.jpg?v=1788369909","url":"https:\/\/voomisupply.com\/products\/rotor-clip-sh-250st-pa-external-snap-retaining-ring","provider":"Voomi Supply","version":"1.0","type":"link"}
