Manufactured from SAE 1060-1090 spring steel with a cadmium finish, this ring seats into a machined groove on a 1-1\/4 inch shaft and provides axial retention of components such as bearings, gears, and housings. The ring measures 0.05 inches thick and 0.056 inches in groove width, with a hardness rating of 47-52 HRC. It meets Military Specification MS 16624-1125 and conforms to SAE 1060-1090 and UNS G10600-G10900 standards. Machinists, maintenance technicians, and mechanical assembly professionals install this ring using standard external retaining ring pliers.\u003c\/p\u003e\n\u003cp\u003eThis retaining ring is suited for rotating and stationary shaft assemblies in industrial machinery, power transmission equipment, pumps, motors, and drive systems where a 1-1\/4 inch shaft diameter is present. The cadmium plating provides corrosion resistance in moderate service environments. It is appropriate for applications that require compliance with military or aerospace-adjacent fastener standards, including those governed by MS 16624-1125. The compact groove depth of 0.037 inches keeps shaft material removal minimal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFits 1-1\/4 inch (31.75 mm) shaft diameter with 1.176 inch groove diameter\u003c\/li\u003e\n  \u003cli\u003eSAE 1060-1090 spring steel construction with 47-52 HRC hardness\u003c\/li\u003e\n  \u003cli\u003eCadmium finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets Military Specification MS 16624-1125\u003c\/li\u003e\n  \u003cli\u003eConforms to SAE 1060-1090, UNS G10600-G10900, and ISO 13485:2015\u003c\/li\u003e\n  \u003cli\u003eRing thickness of 0.05 inches with tight tolerance of plus or minus 0.002 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style external retaining ring for 1-1\/4 inch shaft diameter applications requiring a grooved shaft seat.

Power down and de-energize any equipment before servicing shaft assemblies. Inspect the shaft groove for burrs or damage that could prevent proper ring seating or cause premature disengagement. Do not hammer or pry the ring into position, as this can deform the ring and compromise retention capacity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 1.25 inches (31.75 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 1.176 inches (29.87 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: 1.156 inches (29.36 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 1.69 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: 0.037 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Thickness\u003c\/strong\u003e: 0.05 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\u003eMaterial\u003c\/strong\u003e: Spring Steel, 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: Cadmium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: MS 16624-1125\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: 0.0059 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-125ST MCD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51691961647410,"sku":"SH-125ST MCD","price":10467.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3e077692b2225ff8e5ed825305a238f.jpg?v=1788291453","url":"https:\/\/voomisupply.com\/products\/rotor-clip-sh-125st-mcd-external-retaining-ring-1-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
