Manufactured from 1060-1090 grade spring steel with a phosphate finish, this ring delivers reliable axial retention under mechanical load. It measures 0.093 inches in ring thickness and seats in a groove measuring 0.103 inches wide and 0.081 inches deep. The phosphate coating provides baseline corrosion resistance and lubricity for installation. Maintenance technicians, millwrights, and mechanical assemblers working on industrial shafts, gearboxes, pumps, and rotating assemblies will encounter this ring type in standard repair and build workflows.\u003c\/p\u003e\u003cp\u003eThis retaining ring is suited for use in industrial and commercial mechanical assemblies where a 3-inch nominal shaft diameter is present. Typical applications include pump shafts, motor shafts, gearbox assemblies, and other rotating equipment requiring positive axial component retention. The phosphate finish makes it appropriate for moderately demanding environments where a light protective coating is acceptable. It is sold individually with a minimum order quantity of 10 units per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExternal snap ring design seats in a 2.838-inch groove diameter for secure axial retention\u003c\/li\u003e\n\u003cli\u003e1060-1090 spring steel construction with a hardness rating of 47-52 HRC for consistent spring-back and durability\u003c\/li\u003e\n\u003cli\u003ePhosphate finish provides corrosion resistance and aids installation lubricity\u003c\/li\u003e\n\u003cli\u003eGroove width of 0.103 inches and groove depth of 0.081 inches for precise fit\u003c\/li\u003e\n\u003cli\u003eFree diameter of 2.775 inches and free outside diameter of 2.976 inches\u003c\/li\u003e\n\u003cli\u003eManufactured to ISO 13485:2016 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style external snap retaining ring for 3-inch nominal shaft diameter applications in industrial and commercial rotating equipment assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and removal of external snap retaining rings should be performed by qualified mechanical technicians using appropriate snap ring pliers rated for the ring size. Always de-energize and lock out the equipment per OSHA lockout-tagout procedures before servicing any rotating shaft assembly. Ensure the shaft groove is clean and free of burrs before seating the ring. Wear appropriate eye protection, as snap rings can release under tension during installation or removal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 2.838 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: 2.775 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Diameter Tolerance\u003c\/strong\u003e: -0.030 to 0.020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 2.976 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.103 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Width Tolerance\u003c\/strong\u003e: 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Depth\u003c\/strong\u003e: 0.081 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Thickness\u003c\/strong\u003e: 0.093 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: 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: ISO 13485:2016\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.052 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: SH-300ST PA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51694742733106,"sku":"SH-300ST PA","price":52.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8d36ce26ed49cb16f1f1c37fa3ba4ebd_71dd0776-e460-480c-81c0-e4a7324cd456.jpg?v=1788327920","url":"https:\/\/voomisupply.com\/products\/rotor-clip-sh-300st-pa-external-snap-retaining-ring-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
