It mounts directly to a keyed shaft and joins to a matching hub via a compatible tire coupling element. The hub is machined from steel with a round keyed bore of 1-5\/8 inches, a bore tolerance of +0.0005 to +0.0015 inches, and a hub diameter of 2.6 inches. Rated torque is 550 inch-pounds with a maximum operating speed of 7,500 RPM. The coupling accommodates both angular misalignment up to 4 degrees and parallel misalignment up to 0.0625 inches. No lubrication is required during service life.\u003c\/p\u003e\n\u003cp\u003eThis hub is suited for a wide range of industrial drive applications including blowers, compressors, fans, generators, pumps, and motors. It is designed for use in both standard and spacer element assemblies, since the same hub design is shared across both configurations. Power capacity scales with speed: 10 hp at 1,160 RPM, 15 hp at 1,750 RPM, and 31 hp at 3,500 RPM. The operating temperature range of -40 degrees F to 200 degrees F makes it appropriate for demanding environments. The hub is also rated as chemical resistant and oil resistant.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWE4 coupling size with 1-5\/8 inch round keyed bore and 3\/8 inch keyway width\u003c\/li\u003e\n  \u003cli\u003eRated torque of 550 inch-pounds with a maximum speed of 7,500 RPM\u003c\/li\u003e\n  \u003cli\u003eAccommodates up to 4 degrees angular misalignment and 0.0625 inches parallel misalignment\u003c\/li\u003e\n  \u003cli\u003eNo lubrication required — reduces maintenance intervals\u003c\/li\u003e\n  \u003cli\u003eSame hub used for both standard and spacer tire coupling element assemblies\u003c\/li\u003e\n  \u003cli\u003eChemical resistant and oil resistant steel construction\u003c\/li\u003e\n  \u003cli\u003eSet screw positioned over keyway with 1\/2 inch-13 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.

De-energize and lock out the drive system completely before mounting or removing coupling hubs. Verify shaft diameter and keyway dimensions match the bore and keyway specifications before pressing the hub onto the shaft. Torque the set screw over the keyway per the coupling manufacturer's published guidelines; do not substitute fasteners outside the specified 1\/2 inch-13 thread size.\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\u003eRated Torque\u003c\/strong\u003e: 550 inch-pounds\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\u003eMaximum Speed\u003c\/strong\u003e: 7,500 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorsional Stiffness\u003c\/strong\u003e: 5,370 inch-pounds per radian\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\u003eBore Diameter\u003c\/strong\u003e: 1-5\/8 inches\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\u003eBore Type\u003c\/strong\u003e: Round Keyed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Width\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Depth\u003c\/strong\u003e: 3\/16 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\u003eHub Material\u003c\/strong\u003e: Steel\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\u003eSet Screw Location\u003c\/strong\u003e: Over Keyway\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Thread Size\u003c\/strong\u003e: 1\/2 inch-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.9 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-WE4H158\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TB WOODS","offers":[{"title":"Default Title","offer_id":51383749542194,"sku":"TB-WE4H158","price":147.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670043.jpg?v=1782606258","url":"https:\/\/voomisupply.com\/products\/tb-woods-tb-we4h158-tire-coupling-hub-we4-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
