Manufactured from 1060\/1090 spring steel with a phosphate finish, this ring delivers reliable axial retention in applications where consistent thrust load capacity is critical. The ring carries a groove safety factor thrust load capacity of 2,080 pounds and a ring safety factor of 5,227 pounds. At 0.042 inches thick with a free outer diameter of 0.971 inches, it fits a 7\/8-inch bore. Licensed technicians and maintenance professionals in industrial, mechanical, and OEM assembly environments regularly specify this ring for dependable, low-profile fastening.\u003c\/p\u003e\u003cp\u003eThis internal retaining ring is suited for use in precision bore assemblies across industrial machinery, mechanical drives, fluid power components, and related equipment requiring axial load control. It seats in a groove measuring 0.046 inches wide and 0.028 inches deep. Groove diameter tolerance is -0.0030 to 0.0030 inches, and groove width tolerance is 0.000 to 0.003 inches. Applications span both original equipment manufacturing and maintenance-repair-overhaul scenarios where a compact, reliable internal ring is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/8-inch bore diameter with 0.971-inch free outer diameter for precise internal seating\u003c\/li\u003e\n\u003cli\u003eSpring steel construction, material grade 1060\/1090, for high hardness and elasticity\u003c\/li\u003e\n\u003cli\u003ePhosphate finish provides baseline corrosion resistance and lubricity during installation\u003c\/li\u003e\n\u003cli\u003eRockwell 30N hardness rating of 66-71 for consistent performance under load\u003c\/li\u003e\n\u003cli\u003eThrust load capacity of 2,080 pounds (groove safety factor) and 5,227 pounds (ring safety factor)\u003c\/li\u003e\n\u003cli\u003eConforms to SAE 1060-1090, UNS G10600-G10900, and ISO 13485:2016 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style internal snap retaining ring for 7\/8-inch bore housings machined to standard groove dimensions of 0.046 inches width and 0.028 inches depth.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and removal should be performed by a qualified mechanic or maintenance technician using the correct internal snap ring pliers sized for the ring diameter. Always power down and de-energize any equipment before disassembling the housing. Avoid overexpanding the ring during installation, as exceeding the elastic limit of the material will permanently deform the ring and compromise retention. Inspect the groove for burrs or damage before seating the ring to ensure full groove engagement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Outer Diameter\u003c\/strong\u003e: 0.971 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: 2,080 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrust Load Capacity (Ring Safety Factor)\u003c\/strong\u003e: 5,227 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Spring Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 1060\/1090\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Phosphate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: Rockwell 30N 66-71\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE 1060-1090, UNS G10600-G10900, ISO 13485:2016\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Type\u003c\/strong\u003e: Internal Snap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.00217 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: HO-87ST PA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51715659923762,"sku":"HO-87ST PA","price":2498.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9dde5ffa3478364f8be94395893991bd_a4f3a05e-3d7a-495b-b7d0-a1de14e152dd.jpg?v=1788516900","url":"https:\/\/voomisupply.com\/products\/rotor-clip-ho-87st-pa-internal-snap-retaining-ring","provider":"Voomi Supply","version":"1.0","type":"link"}
