Manufactured from SAE 1060-1090 spring steel (UNS G10600-G10900) with a cadmium-plated finish, this ring seats in a machined external groove on a 1.375-inch diameter shaft. The groove diameter is 1.291 inches with a ring thickness of 0.050 inches. Hardness is rated at 47-52 HRC, providing the spring tension needed to maintain a firm seat under load. Mechanical assemblers, maintenance technicians, and industrial tradespeople install this type of ring during shaft-and-bearing or shaft-and-gear assembly operations.\u003c\/p\u003e\n\u003cp\u003eThis retaining ring is suited for use in mechanical power transmission, rotating shaft assemblies, pump and motor shafts, and similar industrial applications requiring a low-profile external groove fastener. The cadmium plating provides corrosion resistance in environments where bare steel is insufficient. The ring meets Military Specification MS 16624-1137 and ISO 13485:2015 standards, making it appropriate for both general industrial and regulated-industry assembly applications. Minimum order quantity is 100 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFits 1.375-inch (1-3\/8 inches) external shaft diameter with a 1.291-inch groove diameter\u003c\/li\u003e\n  \u003cli\u003eSAE 1060-1090 spring steel construction, hardness 47-52 HRC for reliable spring retention\u003c\/li\u003e\n  \u003cli\u003eCadmium-plated finish for corrosion resistance in demanding environments\u003c\/li\u003e\n  \u003cli\u003eMeets Military Specification MS 16624-1137 and ISO 13485:2015\u003c\/li\u003e\n  \u003cli\u003eRing thickness of 0.050 inches with tight tolerance of plus or minus 0.002 inches\u003c\/li\u003e\n  \u003cli\u003eGroove width of 0.056 inches accommodates standard external groove profiles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style external retaining ring for 1.375-inch diameter shafts with a 1.291-inch groove diameter machined to standard external groove specifications per SAE 1060-1090 and MS 16624-1137.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eExternal retaining rings of this type are installed and removed by mechanical assemblers or maintenance technicians using retaining ring pliers sized for external rings. The shaft assembly should be de-energized and de-pressurized before service. Ensure the groove is clean and free of burrs before seating the ring to avoid improper seating or ring distortion. Do not over-spread the ring during installation, as exceeding the elastic limit will permanently deform the ring and compromise retention.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 1.375 inches (34.93 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 1.291 inches (32.79 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: -0.004 to +0.004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Diameter\u003c\/strong\u003e: 1.272 inches (32.31 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Diameter Tolerance\u003c\/strong\u003e: -0.015 to +0.010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 1.800 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Thickness\u003c\/strong\u003e: 0.050 inches (1.27 mm)\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\u003eGroove Width\u003c\/strong\u003e: 0.056 inches (1.42 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width Tolerance\u003c\/strong\u003e: +0.000 to +0.004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Depth\u003c\/strong\u003e: 0.042 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\u003eHardness\u003c\/strong\u003e: 47-52 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Cadmium-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: MS 16624-1137\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: 0.0072 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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-137ST MCD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51694699479346,"sku":"SH-137ST MCD","price":11912.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf5d305f704adc3e4725ee3cc777a48e.jpg?v=1788327403","url":"https:\/\/voomisupply.com\/products\/rotor-clip-sh-137st-mcd-external-retaining-ring-1-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
