It features a finished bore with keyway and set screw, allowing direct mounting to a compatible shaft. With a 7\/8 inch bore diameter and a hub outside diameter of 1.85 inches, this hub mates with a corresponding tire coupling element to transmit torque between shafts. Rated at 0.3 horsepower at 100 RPM and capable of up to 7,500 RPM, it suits light-duty power transmission applications. The hub is constructed from low carbon steel and cast iron for durability in industrial drive setups. Installation is straightforward for millwrights and mechanical contractors familiar with flexible coupling systems.\u003c\/p\u003e\n\u003cp\u003eThis hub is used in industrial and commercial power transmission systems where a flexible tire-style coupling is required to connect two shafts. The WE2 coupling size code 2 designation identifies the hub as part of the WE2 series, pairing with the corresponding tire element and a matching hub on the driven side. Typical applications include pumps, fans, compressors, and conveyor drives where shock absorption and slight misalignment tolerance are required. Its compact length through bore of 0.94 inches suits tight drive train configurations.\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\u003e7\/8 inch bore diameter fits standard shaft sizes in the WE2 coupling range\u003c\/li\u003e\n  \u003cli\u003eFlanged hub design for positive engagement with the tire coupling element\u003c\/li\u003e\n  \u003cli\u003eRated up to 7,500 RPM for higher-speed drive applications\u003c\/li\u003e\n  \u003cli\u003eLow carbon steel and cast iron construction for mechanical durability\u003c\/li\u003e\n  \u003cli\u003eWE2 series coupling size code 2 for straightforward replacement or assembly sourcing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or assembly component for WE2 series tire coupling systems requiring a flanged shaft hub with a 7\/8 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. Disconnect and lock out all power to the drive system before handling any coupling components. Ensure the shaft and bore are clean and free of burrs before pressing or sliding the hub into position. Verify alignment of the coupled shafts to within the tolerance of the tire element before returning the drive to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Outside Diameter\u003c\/strong\u003e: 1.85 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Through Bore\u003c\/strong\u003e: 0.94 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size Code\u003c\/strong\u003e: 2\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\u003eHub Type\u003c\/strong\u003e: Flanged Shaft Hub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower at 100 RPM\u003c\/strong\u003e: 0.3 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\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: 0.35 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-WE2H78\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TB WOODS","offers":[{"title":"Default Title","offer_id":51383945724210,"sku":"TB-WE2H78","price":132.27,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/tb-woods-tb-we2h78-tire-coupling-hub-7-8-inch-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
