It fits a 7\/32 inch (0.2188 inch decimal) shaft diameter and seats in a groove measuring 0.188 inches in diameter and 0.029 inches wide. Manufactured from SAE 1060-1090 steel and finished with a yellow zinc dichromate coating, this ring provides corrosion resistance in light-duty service environments. The three-prong E style design allows for quick installation and removal without special tooling in most applications. Mechanical assemblers and maintenance technicians working in industrial, HVAC, and general trade settings use this ring as a standard fastening component.\u003c\/p\u003e\n\u003cp\u003eThis retaining ring is suited for use on small-diameter shafts in light mechanical assemblies where space is limited and a full circumferential groove is not practical. Common applications include motor shafts, linkage pins, and small rotating assemblies found in HVAC equipment, plumbing valves, and electrical actuator mechanisms. The E style form factor is particularly useful in assemblies requiring frequent disassembly for maintenance. This ring is sold individually with a minimum order quantity of 100 units, making it appropriate for shop stock or service kit replenishment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eE style three-prong design allows tool-free or needle-nose plier installation on small shafts\u003c\/li\u003e\n  \u003cli\u003eFits 7\/32 inch (0.2188 inch) shaft diameter with a 0.188 inch groove diameter\u003c\/li\u003e\n  \u003cli\u003eSAE 1060-1090 steel construction meets UNS G10600-G10900 and ISO 13485:2015 standards\u003c\/li\u003e\n  \u003cli\u003eYellow zinc dichromate finish provides moderate corrosion protection\u003c\/li\u003e\n  \u003cli\u003eHardness rated at 66.5-71 HR30N for reliable retention under load\u003c\/li\u003e\n  \u003cli\u003eRing thickness of 0.025 inches with a free outside diameter of 0.437 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service stock retaining ring for external shaft retention applications requiring a 7\/32 inch shaft diameter and a 0.188 inch groove diameter E style fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and removal of E style retaining rings is typically performed by mechanical assemblers or field technicians using needle-nose pliers or dedicated retaining ring pliers. Always de-energize and lock out equipment before servicing any assembly containing this ring. Do not reuse a ring that has been removed, as deformation during extraction compromises retention force. Verify groove dimensions against the ring specifications before installation to ensure proper seating and retention.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Type\u003c\/strong\u003e: E Style External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 7\/32 inch (0.2188 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 0.188 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: 0.0000 to 0.0020 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: 0.0000 to 0.0030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Depth\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Diameter\u003c\/strong\u003e: 0.185 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Diameter Tolerance\u003c\/strong\u003e: -0.0030 to 0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 0.437 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: -0.0020 to 0.0020 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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: SAE 1060-1090 (UNS G10600-G10900)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 66.5-71 HR30N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Yellow Zinc Dichromate\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0005 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: SE-21ST ZD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51700886405426,"sku":"SE-21ST ZD","price":922.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07654425de83b9a8dbb5fb9cecf48ffe_59db1fec-11c3-4f70-986e-53e8c969b938.jpg?v=1788395382","url":"https:\/\/voomisupply.com\/products\/rotor-clip-se-21st-zd-e-style-retaining-ring-7-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
