Manufactured from SAE 1060-1090 steel (UNS G10600-G10900), the ring carries an oil finish that provides short-term corrosion protection during storage and handling. It fits a 1-3\/8 inch shaft diameter with a groove diameter of 1.291 inches and a ring thickness of 0.05 inches. Machinists, maintenance technicians, and assemblers working with rotating shafts, gearboxes, pumps, and drive assemblies commonly use this ring type.\u003c\/p\u003e\n\u003cp\u003eThis external spiral retaining ring is suited for industrial and mechanical assembly applications where a shaft-mounted axial stop is required. Typical installations include motor shafts, pump housings, conveyor drive components, and general power-transmission assemblies. The spiral design allows the ring to be wound on and off the shaft groove without snap-ring pliers, making it practical in high-volume assembly environments or confined spaces where standard circlip tools are difficult to use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal spiral design seats in an external shaft groove, no snap-ring pliers required for installation or removal\u003c\/li\u003e\n  \u003cli\u003eSAE 1060-1090 steel construction (UNS G10600-G10900) for reliable strength in mechanical assembly applications\u003c\/li\u003e\n  \u003cli\u003eOil finish provides short-term corrosion protection during storage and transit\u003c\/li\u003e\n  \u003cli\u003eGroove diameter of 1.291 inches with a groove width of 0.056 inches and groove depth of 0.042 inches\u003c\/li\u003e\n  \u003cli\u003eRing thickness of 0.05 inches; free outside diameter of 1.513 inches; free diameter of 1.277 inches\u003c\/li\u003e\n  \u003cli\u003eConforms to SAE 1060-1090, UNS G10600-G10900, and ISO 13485:2015 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style external spiral retaining ring for shafts with a 1-3\/8 inch nominal diameter and a groove machined to 1.291 inches diameter, 0.056 inches wide, and 0.042 inches deep per standard external spiral ring groove specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or mechanical assemblers. Ensure the shaft groove dimensions match the ring specifications before installation, and confirm the shaft and groove are clean and free of burrs that could deform the ring or prevent proper seating. Because this is a spiral-wound ring, it is wound into the groove by hand or with a winding tool rather than expanded with pliers. Do not modify the ring or groove dimensions to force fitment, as this compromises the axial retention load capacity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1-3\/8 inches (1.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter\u003c\/strong\u003e: 1.291 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: -0.004 to +0.004 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 +0.004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Depth\u003c\/strong\u003e: 0.042 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\u003eFree Diameter\u003c\/strong\u003e: 1.277 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Diameter Tolerance\u003c\/strong\u003e: -0.013 to 0.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 1.513 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: SAE 1060-1090 Steel (UNS G10600-G10900)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Oil over Steel\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: 0.00742 pounds\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: CG-137ST OIL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51693559513394,"sku":"CG-137ST OIL","price":2660.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d37af75c4ec5a846765a437f8b1b0251_7a050fc6-1e02-4a97-accf-c4bc483117d8.jpg?v=1788314085","url":"https:\/\/voomisupply.com\/products\/rotor-clip-cg-137st-oil-spiral-retaining-ring-1-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
