Manufactured from spring steel with a phosphate finish, it fits a 5\/16 inch shaft diameter and a groove diameter of 0.25 inches. Ring thickness measures 0.025 inches, and the phosphate coating provides baseline corrosion resistance. This ring ships in a package quantity of 25. Licensed mechanics, maintenance technicians, and industrial assembly professionals are the typical installers of this fastener type.\u003c\/p\u003e\u003cp\u003eE style retaining rings are widely used in light-duty to medium-duty mechanical assemblies where a low-profile, push-on fastening solution is required. Typical applications include shafts on small motors, gearboxes, pumps, and appliance components where axial retention of pulleys, bearings, or spacers is needed. The E style configuration allows tool-free installation by pushing the ring radially over the shaft groove without requiring a dedicated retaining ring installation tool in most light-load scenarios. This part is sold in packs of 25, making it practical for service stock or small production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eE style external design seats radially onto shaft groove for fast installation\u003c\/li\u003e\n\u003cli\u003eSpring steel construction provides reliable retention force and long service life\u003c\/li\u003e\n\u003cli\u003ePhosphate finish offers baseline corrosion resistance for general-purpose environments\u003c\/li\u003e\n\u003cli\u003e0.025 inch ring thickness with a tolerance of -0.002 to 0.002 inches for consistent fit\u003c\/li\u003e\n\u003cli\u003eGroove width of 0.029 inches with a tolerance of -0.000 to 0.003 inches\u003c\/li\u003e\n\u003cli\u003eISO 13485:2016 standard compliance noted in manufacturer specifications\u003c\/li\u003e\n\u003cli\u003ePackage quantity of 25 suitable for service inventory or batch assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style external E style retaining ring for shafts with a 5\/16 inch diameter and a machined groove diameter of 0.250 inches, suitable for general mechanical assemblies requiring axial component retention.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified mechanical technicians or industrial assemblers. Always de-energize and lockout the equipment before disassembling any shaft assembly. Verify the shaft groove dimensions match the ring specifications before installation to ensure proper seating and retention. Do not reuse a retaining ring that has been removed, as the spring steel may be fatigued and retention force compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: -0.0000 to 0.0030 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Diameter (ID)\u003c\/strong\u003e: 0.243 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 0.500 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: 0.031 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\u003eMaterial\u003c\/strong\u003e: Spring Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Phosphate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\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\u003ePackage Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: SE-31ST PA-25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51699563790642,"sku":"SE-31ST PA-25","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74eb11f14bb02cef51a349273b2a6ddf.jpg?v=1788377503","url":"https:\/\/voomisupply.com\/products\/rotor-clip-se-31st-pa-25-e-style-retaining-ring-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
