It fits a 1-5\/16 inch (1.3125 inches) shaft diameter with a groove diameter of 1.232 inches. Made from SAE 1060-1090 carbon steel with a phosphate finish, the ring delivers hardness in the 47-52 HRC range for reliable retention under load. This type of fastener is widely used in mechanical assemblies across HVAC equipment, pumps, motors, and general industrial machinery. Installation is performed by mechanical assemblers or maintenance technicians using standard retaining ring pliers.\u003c\/p\u003e\u003cp\u003eThis external retaining ring is suited for shaft-mounted assemblies requiring a compact, low-profile axial retention solution. The phosphate finish provides a baseline level of corrosion resistance and improves lubricant adhesion in service environments. The ring seats into a groove 0.056 inches wide and 0.040 inches deep, with a free diameter of 1.214 inches and a free outside diameter of 1.750 inches. It is sold in a minimum order quantity of 100 pieces per package, making it appropriate for production or maintenance stocking applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExternal style ring for shaft-groove retention on 1-5\/16 inch shafts\u003c\/li\u003e\n\u003cli\u003eSAE 1060-1090 carbon steel construction with 47-52 HRC hardness\u003c\/li\u003e\n\u003cli\u003ePhosphate finish for corrosion resistance and lubrication retention\u003c\/li\u003e\n\u003cli\u003eGroove diameter of 1.232 inches with tolerance of -0.0040 to 0.0040 inches\u003c\/li\u003e\n\u003cli\u003eRing thickness of 0.050 inches for a low-profile axial footprint\u003c\/li\u003e\n\u003cli\u003eMeets SAE 1060-1090, UNS G10600-G10900, and ISO 13485:2015 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style external retaining ring for shafts with a 1-5\/16 inch diameter and a matching groove profile per SAE 1060-1090 and UNS G10600-G10900 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and removal require retaining ring pliers sized for external rings of this diameter — do not use substitute tools that may deform the ring or damage the groove. Depressurize and de-energize any associated assembly before servicing components secured by this ring. Verify that the shaft groove dimensions match the specified groove width of 0.056 inches and groove depth of 0.040 inches before installation. Reuse of removed retaining rings is generally not recommended in safety-critical or high-cycle applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 1-5\/16 inches (1.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Diameter (mm)\u003c\/strong\u003e: 33.34 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 1.232 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: -0.0040 to 0.0040 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Diameter\u003c\/strong\u003e: 1.214 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Diameter Tolerance\u003c\/strong\u003e: -0.0150 to 0.0100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 1.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.056 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Width Tolerance\u003c\/strong\u003e: 0.0000 to 0.0040 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Depth\u003c\/strong\u003e: 0.040 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Thickness\u003c\/strong\u003e: 0.050 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Thickness Tolerance\u003c\/strong\u003e: -0.0020 to 0.0020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: SAE 1060-1090 Carbon Steel\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: 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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0068 pounds\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: SH131ST PA B100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51720485208370,"sku":"SH131ST PA B100","price":7221.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/63606efc283ac15f53957b22fc2e872c.jpg?v=1788564817","url":"https:\/\/voomisupply.com\/products\/rotor-clip-sh131st-pa-b100-external-retaining-ring","provider":"Voomi Supply","version":"1.0","type":"link"}
