Manufactured from 1060\/1090 spring steel with a phosphate finish, this ring delivers reliable axial retention in assemblies where shaft or bore retention is critical. With a 0.375 inch bore diameter and a free outer diameter of 0.415 inches, the HO-37ST PA is engineered to precise dimensional tolerances and carries a thrust load capacity of 1,066 pounds at the ring safety factor and 350 pounds at the groove safety factor. It is installed and removed using standard internal snap ring pliers.\u003c\/p\u003e\u003cp\u003eThis internal retaining ring is suited for light-to-medium duty mechanical assemblies found in HVAC equipment, pump housings, gearboxes, electric motors, and similar manufactured components. It is commonly used in both original equipment manufacturing and field repair applications where a compact, low-profile axial retention solution is required inside a bored housing. The phosphate finish provides a degree of corrosion resistance suitable for controlled-environment and light-industrial service.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInternal snap ring design seats in a machined bore groove for axial component retention\u003c\/li\u003e\n\u003cli\u003e1060\/1090 spring steel construction with phosphate finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eGroove width of 0.029 inches with a tolerance of 0.000 to 0.003 inches for precise fit\u003c\/li\u003e\n\u003cli\u003eRing thickness of 0.025 inches with a tolerance of -0.002 to 0.002 inches\u003c\/li\u003e\n\u003cli\u003eThrust load capacity: 1,066 pounds (ring safety factor) and 350 pounds (groove safety factor)\u003c\/li\u003e\n\u003cli\u003eHardness rated at Rockwell 30N 69.5-73 for consistent spring-back performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style internal retaining ring for bored housings with a 0.375 inch bore diameter and a groove width of 0.029 inches.

De-energize and lock out any equipment before servicing assemblies that contain this retaining ring. Verify that the bore groove dimensions match the ring specifications prior to installation, as improper groove fit can compromise thrust load capacity. This ring is typically installed by millwrights, HVAC technicians, pump mechanics, or assembly technicians working to applicable equipment service standards.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Type\u003c\/strong\u003e: Internal Snap Ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Outer Diameter\u003c\/strong\u003e: 0.415 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: -0.002 to 0.002 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: 0.000 to 0.003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Depth\u003c\/strong\u003e: 0.011 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Diameter 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\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 69.5-73\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrust Load Capacity (Ring Safety Factor)\u003c\/strong\u003e: 1,066 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrust Load Capacity (Groove Safety Factor)\u003c\/strong\u003e: 350 pounds\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\u003eUNSPSC Code\u003c\/strong\u003e: 31163202\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.00025 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-37ST PA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51701118730546,"sku":"HO-37ST PA","price":1436.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bce52e2d856a3ca1fe7ae2e0ae459552.jpg?v=1788398414","url":"https:\/\/voomisupply.com\/products\/rotor-clip-ho-37st-pa-internal-snap-retaining-ring","provider":"Voomi Supply","version":"1.0","type":"link"}
