Manufactured from 15-7 grade 632 stainless steel (AMS-5529, UNS S15700), this ring is suited for applications requiring corrosion resistance and elevated hardness. It fits a 7\/8 inch (0.875 inch) shaft diameter with a groove diameter of 0.675 inches and a ring thickness of 0.05 inches. Hardness is rated at 37-43 HRC. The three-prong E style design allows for tool-free or plier-assisted installation from the side of the shaft, which is useful in confined assemblies where snap ring pliers cannot access the shaft end.\u003c\/p\u003e\u003cp\u003eThis retaining ring is used across industrial, mechanical, and trade equipment assemblies wherever a 7\/8 inch shaft requires external retention in a standard E style groove. Typical applications include pump shafts, motor shafts, actuator assemblies, and similar rotating or sliding components found in HVAC equipment, fluid handling systems, and electrical drive assemblies. The stainless steel construction makes it appropriate for wet or corrosive environments where carbon steel rings would degrade. Installation is performed by maintenance technicians and mechanical assemblers as part of component replacement or new assembly work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eE style external retaining ring with 3-prong design for side-loading installation on shaft\u003c\/li\u003e\n\u003cli\u003e15-7 grade 632 stainless steel construction resists corrosion in wet or chemically active environments\u003c\/li\u003e\n\u003cli\u003eHardness of 37-43 HRC provides strong retention under dynamic and axial loading\u003c\/li\u003e\n\u003cli\u003eGroove diameter of 0.675 inches with a tight groove diameter tolerance of 0.000 to 0.003 inches for precise fitment\u003c\/li\u003e\n\u003cli\u003eRing thickness of 0.05 inches with a tolerance of -0.002 to 0.002 inches\u003c\/li\u003e\n\u003cli\u003eMeets AMS-5529, UNS S15700, and ISO 13485:2015 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style external E style retaining ring for 7\/8 inch shaft diameter applications requiring a groove diameter of 0.675 inches.

Always de-energize and lock out the equipment before servicing any shaft assembly. Inspect the shaft groove for burrs, corrosion, or dimensional non-conformance before seating the ring. Do not reuse a ring that has been deformed or over-stressed during a previous removal.\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\/8 inches (0.875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 0.675 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\u003eFree Diameter\u003c\/strong\u003e: 0.668 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Diameter Tolerance\u003c\/strong\u003e: -0.005 to 0.003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 1.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.056 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: 0.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Thickness\u003c\/strong\u003e: 0.05 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: 15-7 Grade 632 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 37-43 HRC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Prongs\u003c\/strong\u003e: 3\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: 5\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-87SS B100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51710741315890,"sku":"E-87SS B100","price":2795.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5e6edf1259710cb7c524502ba19755e_8a382e1a-528f-4181-90fa-c875acea4dbd.jpg?v=1788470026","url":"https:\/\/voomisupply.com\/products\/rotor-clip-e-87ss-b100-external-e-style-retaining-ring","provider":"Voomi Supply","version":"1.0","type":"link"}
