It features a finished bore with keyway and set screw, accepting a 1.375-inch shaft. The hub outside diameter measures 2.32 inches with a length through bore of 1.5 inches. Constructed from low carbon steel with a cast iron hub body, this component is rated for up to 0.58 horsepower at 100 RPM and a maximum speed of 7,500 RPM. Licensed mechanics and millwrights install this hub as part of a matched tire coupling system to transmit torque between shafts while absorbing vibration and minor misalignment.\u003c\/p\u003e\n\u003cp\u003eThis tire coupling hub is suited for light- to medium-duty power transmission applications in industrial and commercial equipment. It mounts directly to a compatible shaft and joins with a matched tire coupling element and a corresponding hub to complete the flexible coupling assembly. The WE3 size code indicates the coupling series, so the mating tire element and opposing hub must match this designation. Common applications include pumps, compressors, fans, and conveyor drives where flexible shaft coupling is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore with keyway and set screw for secure shaft engagement\u003c\/li\u003e\n  \u003cli\u003e1.375-inch bore diameter fits standard keyed shaft configurations\u003c\/li\u003e\n  \u003cli\u003eFlanged hub design mates with WE3 series tire coupling elements\u003c\/li\u003e\n  \u003cli\u003eRated to 7,500 RPM maximum speed\u003c\/li\u003e\n  \u003cli\u003eLow carbon steel and cast iron construction for durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003e0.58 horsepower capacity at 100 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service component for WE3 series tire coupling assemblies requiring a flanged shaft hub with a 1.375-inch finished bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified millwright or mechanical technician. Ensure all drive equipment is fully de-energized and locked out before removing or installing coupling components. The shaft and bore should be clean and free of burrs before pressing or sliding the hub into position. Align the coupling assembly within manufacturer-recommended tolerances to avoid premature wear on the tire element.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Type\u003c\/strong\u003e: Finished with Keyway and Set Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size Code\u003c\/strong\u003e: WE3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Outside Diameter\u003c\/strong\u003e: 2.32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Through Bore\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 7,500 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower at 100 RPM\u003c\/strong\u003e: 0.58 hp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Type\u003c\/strong\u003e: Flanged Shaft Hub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Low Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.70 pounds\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-WE3H138\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TB WOODS","offers":[{"title":"Default Title","offer_id":51383883235634,"sku":"TB-WE3H138","price":150.03,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/tb-woods-tb-we3h138-tire-coupling-hub-1-375-in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
