Manufactured from 15-7 stainless steel (Grade 632) and compliant with AMS-5529 and UNS S15700 standards, it provides reliable axial retention where corrosion resistance and high hardness are required. The ring fits a 7\/16 inch shaft diameter with a groove diameter of 0.343 inches and a ring thickness of 0.035 inches. Its three-prong E style design allows for fast installation and removal without specialized tooling, making it well suited for maintenance-intensive applications across industrial, HVAC, and mechanical service environments.\u003c\/p\u003e\u003cp\u003eThis retaining ring is used in applications where a compact, corrosion-resistant fastener is needed on small-diameter shafts. Common install scenarios include blower assemblies, fan shaft retention, pump components, and precision mechanical linkages found in HVAC equipment, plumbing systems, and industrial machinery. The 15-7 stainless steel construction is appropriate for environments exposed to moisture, mild chemicals, or elevated temperatures where carbon steel rings would corrode or lose integrity over time.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eE style external ring with 3-prong design for tool-free snap installation and removal\u003c\/li\u003e\n\u003cli\u003e15-7 stainless steel (Grade 632) construction rated to 37-43 HRC hardness\u003c\/li\u003e\n\u003cli\u003eMeets AMS-5529, UNS S15700, and ISO 13485:2015 standards\u003c\/li\u003e\n\u003cli\u003eShaft diameter: 7\/16 inches (0.4375 inches); groove diameter: 0.343 inches\u003c\/li\u003e\n\u003cli\u003eFree outside diameter of 0.687 inches allows positive retention across the groove\u003c\/li\u003e\n\u003cli\u003eGroove width of 0.039 inches with tolerance of 0.000 to 0.003 inches for precise fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style external retaining ring for 7\/16 inch diameter shafts requiring a 0.343 inch groove diameter; verify groove width and depth specifications against the shaft assembly before installation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eExternal E style retaining rings are typically installed and removed by maintenance technicians and mechanical tradespeople using retaining ring pliers or a flat-blade tool applied to the prongs. Relieve all load from the shaft and de-energize the equipment before servicing any rotating assembly. Confirm groove dimensions match the ring specifications to prevent ring walk or ejection under load. Do not reuse a ring that has been overstressed, deformed, or shows signs of corrosion fatigue.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Type\u003c\/strong\u003e: External E Style\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 7\/16 inches (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 0.343 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: 0.000 to 0.003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.039 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: 0.047 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Diameter\u003c\/strong\u003e: 0.337 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Diameter Tolerance\u003c\/strong\u003e: -0.004 to 0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 0.687 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Thickness\u003c\/strong\u003e: 0.035 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\u003eNumber of Prongs\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 15-7 Grade 632\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 37-43 HRC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: AMS-5529, UNS S15700, 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: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: E-43SS B100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51697202594098,"sku":"E-43SS B100","price":1042.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5e6edf1259710cb7c524502ba19755e_fa119df1-7016-4fa0-ac0f-8d1de63aa7f0.jpg?v=1788350472","url":"https:\/\/voomisupply.com\/products\/rotor-clip-e-43ss-b100-external-e-style-retaining-ring","provider":"Voomi Supply","version":"1.0","type":"link"}
