It seats into a machined groove on the shaft exterior, creating a shoulder that retains bearings, gears, or other assembled components against axial movement. Manufactured from AISI 302 stainless steel with an oil finish coating, this ring offers good corrosion resistance for demanding mechanical environments. The ring measures 0.093 inches thick with a groove diameter of 3.076 inches and a free outside diameter of 3.504 inches. Mechanical assemblers, maintenance technicians, and industrial equipment professionals install this ring as part of shaft assemblies across a range of rotating equipment applications.\u003c\/p\u003e\u003cp\u003eThis retaining ring is suited for use in precision shaft assemblies where a low-profile, spirally wound ring is preferred over a stamped E-ring or traditional Circlip. Typical applications include gearboxes, pump shafts, conveyor rollers, and motor assemblies where the shaft diameter is 3-1\/4 inches and the groove has been machined to the specified dimensions. It is manufactured to AISI 302, AMS-5866, and ISO 13485:2016 standards, making it appropriate for applications requiring documented material and dimensional traceability.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExternal spiral design seats into groove on shaft OD without requiring snap-ring pliers in all configurations\u003c\/li\u003e\n\u003cli\u003eAISI 302 stainless steel construction provides corrosion resistance in wet or chemically exposed environments\u003c\/li\u003e\n\u003cli\u003eMeets AISI 302, AMS-5866, and ISO 13485:2016 standards for material and dimensional compliance\u003c\/li\u003e\n\u003cli\u003eOil finish coating applied at factory for handling and corrosion protection during storage\u003c\/li\u003e\n\u003cli\u003eGroove width of 0.103 inches and groove depth of 0.087 inches for precise machined-groove fitment\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.06 pounds, suitable for weight-sensitive rotating assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for external installation on shafts with a nominal diameter of 3-1\/4 inches (3.2500 inches decimal) and a groove machined to 3.076 inches diameter with a width of 0.103 inches and depth of 0.087 inches, within the specified tolerances.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and removal of spiral retaining rings is typically performed by qualified mechanical assemblers or maintenance technicians using appropriate ring insertion tools. De-energize and lock out all equipment before accessing shaft assemblies. Verify that the shaft groove dimensions fall within the specified tolerance range before installation, as undersized or oversized grooves can result in ring failure under load. Do not reuse a retaining ring that has been removed from service, as the ring may be deformed and unable to provide reliable retention.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Type\u003c\/strong\u003e: External Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 3-1\/4 inches (3.2500 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 3.076 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: -0.0060 to 0.0060 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Diameter\u003c\/strong\u003e: 3.054 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Diameter Tolerance\u003c\/strong\u003e: -0.0300 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 3.504 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: 0.0000 to 0.0050 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Depth\u003c\/strong\u003e: 0.087 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: -0.0030 to 0.0030 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 302 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Oil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: AISI 302, AMS-5866, 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: 0.06 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: CG-325SJ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51715434283314,"sku":"CG-325SJ","price":4844.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29a69c0aa71c152307354dd1c5168e00_c3635260-d2ef-4896-971f-e2380ac483f2.jpg?v=1788513897","url":"https:\/\/voomisupply.com\/products\/rotor-clip-cg-325sj-external-spiral-retaining-ring","provider":"Voomi Supply","version":"1.0","type":"link"}
