Sized at coupling size 8, it features a 1-7\/8 inch round keyed bore with tight tolerances of +0.0005 inch to +0.0015 inch, ensuring a secure, precise shaft fit. The cast iron hub measures 3-1\/4 inches in diameter with a 5-29\/64 inch outside diameter and a hub body length of 3\/4 inch. Rated to 4,500 RPM maximum speed, this flange half mates with a matched sleeve insert to form a complete flexible sleeve coupling assembly. Installation is performed by millwrights and mechanical technicians during drivetrain setup or coupling replacement.\u003c\/p\u003e\n\u003cp\u003eThe TB-8S178 is suited for use in compressor, conveyor, motor, and pump drive trains where angular and parallel misalignment compensation is required. The 4-way flexing action of the sleeve coupling design absorbs shock, vibration, end float, and both angular and parallel misalignment. This makes it a practical choice for industrial facilities running continuous-duty rotating equipment that experiences dynamic loading or slight shaft offset conditions. It is measured and specified in the inch system of measurement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCoupling size 8 with 1-7\/8 inch finished round keyed bore\u003c\/li\u003e\n  \u003cli\u003eBore tolerance of +0.0005 inch to +0.0015 inch for precise shaft fit\u003c\/li\u003e\n  \u003cli\u003e4-way flexing action accommodates angular misalignment, parallel misalignment, end float, and shock\u003c\/li\u003e\n  \u003cli\u003eCast iron hub construction with chemical and oil resistance\u003c\/li\u003e\n  \u003cli\u003eRated to 4,500 RPM maximum speed\u003c\/li\u003e\n  \u003cli\u003eIncludes two set screws — one over the key and one at 90 degrees — with 3\/8 inch-16 thread size\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit flange half for TB WOODS size 8 sleeve coupling assemblies using a matched sleeve insert on inch-dimensioned keyed shafts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a qualified millwright or mechanical technician. Disconnect and lock out all power to the driven equipment before mounting or removing coupling flanges. Ensure shaft surfaces are clean and free of burrs before pressing the bore onto the shaft. Torque set screws to the coupling manufacturer specifications and verify angular and parallel alignment of both shafts after assembly before returning the drive to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 4,500 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5-29\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 1-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Type\u003c\/strong\u003e: Round Keyed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Tolerance\u003c\/strong\u003e: +0.0005 inches \/ +0.0015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Width\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Depth\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Through Bore\u003c\/strong\u003e: 2-3\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 3-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Body Length\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Type\u003c\/strong\u003e: Flange Hub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMisalignment Types\u003c\/strong\u003e: Angular, Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSet Screws Included\u003c\/strong\u003e: 2 — one over the key and one at 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Thread Size\u003c\/strong\u003e: 3\/8 inch-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResistance Properties\u003c\/strong\u003e: Chemical Resistant, Oil Resistant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Mexico (subject to change)\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: TB WOODS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TB-8S178\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TB WOODS","offers":[{"title":"Default Title","offer_id":51383367237938,"sku":"TB-8S178","price":111.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670362.jpg?v=1782594714","url":"https:\/\/voomisupply.com\/products\/tb-woods-tb-8s178-sleeve-coupling-flange-size-8","provider":"Voomi Supply","version":"1.0","type":"link"}
