Manufactured from SAE 1060-1090 spring steel with a cadmium plating finish, this ring fits a 1\/4 inch (0.25 inch) shaft diameter and seats in a groove measuring 0.23 inches in diameter and 0.029 inches wide. The ring is 0.025 inches thick and carries a hardness rating of 69.5 to 73 HRC, providing reliable retention under dynamic and static load conditions. It meets Military Specification MS 16624-1025 and conforms to SAE 1060-1090 and UNS G10600-G10900 standards. Mechanical technicians and maintenance professionals install this ring where precise axial retention is required on small-diameter shafts.\u003c\/p\u003e\n\u003cp\u003eThis external retaining ring is suited for use in light mechanical, hydraulic, pneumatic, and electromechanical assemblies where a 1\/4 inch shaft is present and groove dimensions match the specified tolerances. Common applications include motors, pumps, actuators, valves, and similar precision assemblies found in industrial and commercial equipment. The cadmium finish provides corrosion resistance in moderate-exposure environments. This ring is sold individually but must be ordered in multiples of 100 units per the minimum order quantity requirement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFits 1\/4 inch (0.25 inch) shaft diameter with 0.23 inch groove diameter\u003c\/li\u003e\n  \u003cli\u003eSAE 1060-1090 spring steel construction, hardness 69.5-73 HRC\u003c\/li\u003e\n  \u003cli\u003eCadmium plating finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets Military Specification MS 16624-1025\u003c\/li\u003e\n  \u003cli\u003eConforms to SAE 1060-1090, UNS G10600-G10900, and ISO 13485:2015 standards\u003c\/li\u003e\n  \u003cli\u003eRing thickness of 0.025 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 a standard external retaining ring for mechanical assemblies using a 1\/4 inch shaft with a groove diameter of 0.23 inches, groove width of 0.029 inches, and groove depth of 0.01 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eExternal retaining rings of this type are installed by qualified mechanical technicians using appropriate snap ring pliers sized for the ring ends. De-energize and lock out all power to the assembly before disassembly or ring installation. Inspect the shaft groove for burrs or damage before seating the ring to ensure proper retention and prevent ring failure under load. Do not over-expand the ring during installation, as spring steel at this hardness is susceptible to fracture if stressed beyond its elastic limit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 0.23 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: -0.0015 to +0.0015 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: 0.01 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Diameter\u003c\/strong\u003e: 0.225 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 0.45 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: SAE 1060-1090 Spring Steel (UNS G10600-G10900)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Cadmium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 69.5-73 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: MS 16624-1025\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: 0.0002 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-25ST MCD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51720323432754,"sku":"SH-25ST MCD","price":5438.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/db5b8f850a1292dd28ec4312dcd0b6f6.jpg?v=1788562470","url":"https:\/\/voomisupply.com\/products\/rotor-clip-sh-25st-mcd-external-retaining-ring-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
