It mounts directly to a keyed shaft and connects to a matched tire coupling element to transmit torque between two shafts while accommodating angular and parallel misalignment. The hub is machined from steel with a 1-3\/8 inch round keyed bore, a 5\/16 inch keyway width, and a length through bore of 1-11\/16 inches. Rated at 550 inch-pounds of torque and a maximum speed of 7,500 RPM, this hub is sized for demanding power transmission in industrial and commercial mechanical systems. Licensed mechanics and millwrights are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis hub is suited for use in blowers, compressors, fans, generators, pumps, and motors across numerous industrial applications. It performs across a wide temperature range of -40 degrees F to 200 degrees F and carries chemical and oil resistance properties, making it viable in harsh service environments. At 10 hp at 1,160 RPM, 15 hp at 1,750 RPM, and 31 hp at 3,500 RPM, the WE4 hub handles a broad range of drive configurations in both light and heavy-duty mechanical setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWE4 coupling size with 1-3\/8 inch keyed bore and 1-11\/16 inch length through bore\u003c\/li\u003e\n  \u003cli\u003e550 in-lb rated torque with a torsional stiffness of 5,370 in-lb\/rad\u003c\/li\u003e\n  \u003cli\u003eAccommodates 4 degrees of angular misalignment and 0.0625 inch of parallel misalignment\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 7,500 RPM\u003c\/li\u003e\n  \u003cli\u003eNo lubrication required; absorbs shock loads\u003c\/li\u003e\n  \u003cli\u003eSame hub used for both standard and spacer element assemblies, simplifying parts inventory\u003c\/li\u003e\n  \u003cli\u003eSet screw located over keyway with 1\/4 inch-20 thread size\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with WE4-size Dura-Flex tire coupling elements.

Disconnect and lock out all power to the drive system before mounting or removing any coupling components. Verify shaft diameter and keyway dimensions match the bore and keyway specs of this hub before installation. Torque the set screw over the keyway per applicable mechanical standards and confirm proper alignment of both shafts before returning the system 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: WE4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower at 1,160 RPM\u003c\/strong\u003e: 10 hp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower at 1,750 RPM\u003c\/strong\u003e: 15 hp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower at 3,500 RPM\u003c\/strong\u003e: 31 hp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower at 100 RPM\u003c\/strong\u003e: 0.88 hp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRated Torque\u003c\/strong\u003e: 550 in-lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorsional Stiffness\u003c\/strong\u003e: 5,370 in-lb\/rad\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 7,500 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 1-3\/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: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Depth\u003c\/strong\u003e: 5\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Through Bore\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 2.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Length Standard Assembly\u003c\/strong\u003e: 4.68 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAngular Misalignment\u003c\/strong\u003e: 4 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eParallel Misalignment\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 200 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSet Screw Location\u003c\/strong\u003e: Over Keyway\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Thread Size\u003c\/strong\u003e: 1\/4 inch-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 pounds\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-WE4H138\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TB WOODS","offers":[{"title":"Default Title","offer_id":51383279616306,"sku":"TB-WE4H138","price":192.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670045.jpg?v=1782591964","url":"https:\/\/voomisupply.com\/products\/tb-woods-tb-we4h138-tire-coupling-hub-we4-keyed-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
