With a 7\/8-inch (0.875-inch) bore diameter and a ring thickness of 0.042 inches, this ring is engineered for precision fits in light- to medium-load assemblies. The oil finish provides baseline corrosion resistance during storage and handling. Machinists, maintenance technicians, and mechanical assemblers install this type of ring in production and repair settings where space constraints make standard snap rings impractical.\u003c\/p\u003e\n\u003cp\u003eInternal spiral retaining rings like the KG-87ST OIL are commonly used in gearboxes, pump housings, motor end bells, hydraulic cylinders, and similar assemblies where a bore-retained ring is needed to secure shafts, bearings, pins, or other round components. The spiral design allows tool-free or single-tool installation by winding the ring into the groove, making it well suited for high-volume assembly lines as well as field repair work. This part is appropriate for both industrial and commercial mechanical applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal spiral design installs and removes without specialized pliers, reducing assembly time\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch bore diameter with a free outside diameter of 0.943 inches for consistent groove seating\u003c\/li\u003e\n  \u003cli\u003eOil finish provides corrosion protection during storage and initial service\u003c\/li\u003e\n  \u003cli\u003eThrust load capacity of 1,730 pounds (groove safety factor) and 5,310 pounds (ring safety factor)\u003c\/li\u003e\n  \u003cli\u003eSteel construction (SAE 1060-1090 \/ UNS G10600-G10900) for reliable performance under mechanical load\u003c\/li\u003e\n  \u003cli\u003eMeets ISO 13485:2016 standards; UNSPSC Code 31163202\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style internal spiral retaining ring for 7\/8-inch bore applications requiring a groove width of 0.046 inches and a groove depth of 0.028 inches; verify bore and groove dimensions against your assembly drawings before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanical technicians or assemblers; ensure the bore groove is clean, free of burrs, and machined to the specified tolerances before seating the ring. Disengage all rotating or pressurized systems before removing or installing retaining rings. Wind the ring into the groove using the appropriate spiral ring installation tool to avoid deforming the ring or damaging the groove. Never reuse a retaining ring that has been over-expanded or shows signs of deformation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Type\u003c\/strong\u003e: Internal Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 7\/8 inch (0.875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 0.943 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.773 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Thickness\u003c\/strong\u003e: 0.042 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\u003eGroove Width\u003c\/strong\u003e: 0.046 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: 0.028 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: -0.0030 to 0.0030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrust Load Capacity (Groove Safety Factor)\u003c\/strong\u003e: 1,730 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrust Load Capacity (Ring Safety Factor)\u003c\/strong\u003e: 5,310 pounds\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\u003eFinish\u003c\/strong\u003e: Oil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 13485:2016; UNSPSC 31163202\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: Does not meet military specifications\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.00285 pounds\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\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: KG-87ST OIL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51689088549170,"sku":"KG-87ST OIL","price":1774.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a545ce7de19f57e4c6511ca340ebec8.jpg?v=1788254602","url":"https:\/\/voomisupply.com\/products\/rotor-clip-kg-87st-oil-internal-spiral-retaining-ring","provider":"Voomi Supply","version":"1.0","type":"link"}
