The one-piece split construction allows installation without moving connected equipment. Rated to 1,475 in-lb maximum torque and 4,500 RPM maximum speed, this insert handles angular misalignment up to 1 degree and parallel misalignment up to 0.02 inches. The JES flange type delivers four-way flexing action, making it a reliable flexible element for demanding power transmission applications. Licensed HVAC and mechanical contractors as well as industrial maintenance technicians install this type of coupling insert.\u003c\/p\u003e\n\u003cp\u003eThis coupling insert is suited for a wide range of industrial and commercial power transmission setups. Typical applications include blowers, compressors, conveyors, mixers, motors, and pumps. It operates across a temperature range of -30 degrees F to 275 degrees F, giving it usability in both cold-storage environments and high-heat mechanical rooms. The EPDM material provides chemical resistance and oil resistance, making it appropriate for environments where fluid exposure is a concern. The horsepower rating scales with shaft speed: 2.34 hp at 100 RPM, 28.08 hp at 1,200 RPM, 42.13 hp at 1,800 RPM, and 84.25 hp at 3,600 RPM.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOne-piece split insert design allows installation without disconnecting shafts\u003c\/li\u003e\n  \u003cli\u003eFour-way flexing action absorbs shock, vibration, angular misalignment, parallel misalignment, and end float\u003c\/li\u003e\n  \u003cli\u003eEPDM rubber construction offers chemical resistance and oil resistance\u003c\/li\u003e\n  \u003cli\u003eRated to 1,475 in-lb torque and 4,500 RPM maximum speed\u003c\/li\u003e\n  \u003cli\u003eBroad operating temperature range: -30 degrees F to 275 degrees F\u003c\/li\u003e\n  \u003cli\u003eScales from 2.34 hp at 100 RPM up to 84.25 hp at 3,600 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Size 8 JES-flange replacement sleeve coupling insert for Sure-Flex style couplings using the TB WOODS 8JES body style designation.

Disconnect and lock out all power to the drive system before removing or installing the coupling insert. The one-piece split design allows the insert to be installed radially without shaft separation, but verify flange gap and alignment per the coupling manufacturer guidelines before returning the drive to service. Inspect mating flanges for wear or damage before installing a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Type\u003c\/strong\u003e: JES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Torque\u003c\/strong\u003e: 1,475 in-lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorsional Stiffness\u003c\/strong\u003e: 4,335 in-lb\/rad\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 4,500 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHP Rating at 100 RPM\u003c\/strong\u003e: 2.34 hp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHP Rating at 1,200 RPM\u003c\/strong\u003e: 28.08 hp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHP Rating at 1,800 RPM\u003c\/strong\u003e: 42.13 hp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHP Rating at 3,600 RPM\u003c\/strong\u003e: 84.25 hp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAngular Misalignment\u003c\/strong\u003e: 1 degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eParallel Misalignment\u003c\/strong\u003e: 0.02 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Design\u003c\/strong\u003e: One-Piece Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: EPDM Rubber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResistance Properties\u003c\/strong\u003e: Chemical Resistant, Oil Resistant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range\u003c\/strong\u003e: -30 degrees F to 275 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.13 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: United States\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-8JES\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TB WOODS","offers":[{"title":"Default Title","offer_id":51383955849522,"sku":"TB-8JES","price":136.49,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670039.jpg?v=1782613098","url":"https:\/\/voomisupply.com\/products\/tb-woods-tb-8jes-sure-flex-sleeve-coupling-insert-size-8","provider":"Voomi Supply","version":"1.0","type":"link"}
