Rated for 156 in-lb of torque and a maximum speed of 7,600 RPM, this insert handles both angular and parallel shaft misalignment in demanding mechanical drive applications. Its four-way flexing action absorbs shock, end float, and vibration, protecting connected equipment from dynamic load spikes. Installation is straightforward for mechanical and industrial service technicians working on motor-driven systems across a range of industries.\u003c\/p\u003e\n\u003cp\u003eThe TB-4J is suited for use in blowers, compressors, conveyors, mixers, motors, and pumps in both light commercial and industrial settings. Its EPDM construction provides chemical and oil resistance, making it appropriate for environments where fluid exposure is common. The insert operates reliably across a wide temperature range, from -30 degrees F to 275 degrees F, supporting year-round service in both indoor and outdoor mechanical installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOne-piece solid EPDM construction for reliable torque transmission up to 156 in-lb\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 7,600 RPM\u003c\/li\u003e\n  \u003cli\u003eFour-way flexing action absorbs shock, vibration, misalignment, and end float\u003c\/li\u003e\n  \u003cli\u003eAccommodates angular misalignment up to 1 degree and parallel misalignment up to 0.01 inches\u003c\/li\u003e\n  \u003cli\u003eChemical resistant and oil resistant EPDM material\u003c\/li\u003e\n  \u003cli\u003eWide service temperature range: -30 degrees F to 275 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for size 4 sleeve coupling systems using compatible JE or JN series coupling flanges in standard mechanical drive assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed millwright or mechanical technician. Disconnect and lock out all power to the drive system before removing or installing the coupling insert. Verify shaft alignment is within the specified angular and parallel misalignment tolerances before completing assembly. Follow applicable ANSI and OSHA machine guarding requirements when reinstalling coupling guards after service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRated Torque\u003c\/strong\u003e: 156 in-lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorsional Stiffness\u003c\/strong\u003e: 458 in-lb\/rad\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 7,600 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower at 100 RPM\u003c\/strong\u003e: 0.25 hp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower at Speed\u003c\/strong\u003e: 4.5 hp at 1,800 RPM; 8.9 hp at 3,600 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.3125 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: 0.01 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: -30 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 275 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: EPDM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Construction\u003c\/strong\u003e: One Piece - Solid\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\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA (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-4J\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TB WOODS","offers":[{"title":"Default Title","offer_id":51383003414834,"sku":"TB-4J","price":31.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670298.jpg?v=1782585136","url":"https:\/\/voomisupply.com\/products\/tb-woods-tb-4j-sleeve-coupling-insert-size-4-epdm","provider":"Voomi Supply","version":"1.0","type":"link"}
