Machined from high-strength cast iron, this flange ships bored to size at 1.875 inches for a slip fit on standard shafts. It carries a Size 6 coupling code and is rated to 6000 RPM. The flange diameter and outside diameter are both 4.0000 inches, with a hub end outside diameter of 4 inches and a length through bore of 1-9\/16 inches. Maintenance mechanics and millwrights install these flanges in power transmission applications where easy removal and reinstallation are priorities. The Type S hub flange design simplifies servicing without disturbing connected equipment.\u003c\/p\u003e\n\u003cp\u003eThis spacer flange is used in industrial power transmission systems wherever a TB WOODS sleeve coupling Size 6 is specified. Typical applications include pumps, fans, compressors, and conveyors in light to moderate duty settings. Horsepower capacity varies by sleeve elastomer: 0.7 hp at 100 RPM with EPDM or Neoprene sleeves, and 2.9 hp at 100 RPM with Hytrel sleeves. The bored-to-size configuration fits standard shaft diameters without additional machining, making it ready for direct installation. It is suited to both new builds and replacement service on existing sleeve coupling assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-strength cast iron construction for durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003eBored to size at 1.875 inches for slip fit on standard shafts — no secondary machining required\u003c\/li\u003e\n  \u003cli\u003eType S spacer flange design allows removal without moving connected equipment\u003c\/li\u003e\n  \u003cli\u003eRated to 6000 RPM maximum speed\u003c\/li\u003e\n  \u003cli\u003eCompatible with EPDM, Neoprene, and Hytrel sleeve elastomers at different horsepower ratings\u003c\/li\u003e\n  \u003cli\u003eSize 6 coupling code for straightforward specification and replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement spacer flange for TB WOODS Size 6 sleeve coupling assemblies.

Disconnect and lock out all power to the driven equipment before handling coupling components. Verify shaft diameter matches the 1.875-inch bore before assembly, and inspect mating sleeve and opposing flange for wear before reinstalling. Follow applicable ANSI and OSHA machine guarding requirements after reassembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Type\u003c\/strong\u003e: Bored to Size\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 4.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub End Outside Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Overall Length\u003c\/strong\u003e: 2-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Through Bore\u003c\/strong\u003e: 1-9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size Code\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Flange Type Code\u003c\/strong\u003e: S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Type\u003c\/strong\u003e: Spacer Flange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Strength Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax RPM\u003c\/strong\u003e: 6000 rpm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower at 100 RPM (EPDM and Neoprene)\u003c\/strong\u003e: 0.7 hp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower at 100 RPM (Hytrel)\u003c\/strong\u003e: 2.9 hp\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-6S178\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TB WOODS","offers":[{"title":"Default Title","offer_id":51383894769970,"sku":"TB-6S178","price":85.24,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/tb-woods-tb-6s178-sleeve-coupling-spacer-flange-size-6","provider":"Voomi Supply","version":"1.0","type":"link"}
