This sleeve fits into jaw-style coupling assemblies to transmit torque between shafts while absorbing shock, dampening vibration, and accommodating minor misalignment. It carries a rated torque of 1800 inch-pounds and is sized for a 5\/8 inch minimum bore diameter. The sleeve measures 1.88 inches overall length and 3.75 inches outside diameter, placing it in the Series JE product line. Mechanical maintenance technicians and millwrights install this component during coupling assembly or scheduled replacement intervals on rotating equipment.\u003c\/p\u003e\n\u003cp\u003eThis sleeve insert is used in industrial and commercial drive train applications where a jaw-type flexible coupling connects two shafts on pumps, compressors, fans, conveyors, and similar rotating equipment. The Hytrel material suits environments where moderate chemical exposure, temperature cycling, or dynamic loading would degrade softer elastomers more quickly. It is a direct-fit Series JE sleeve for coupling size code 6 assemblies and is sold as a single piece.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHytrel thermoplastic elastomer construction provides flexibility, fatigue resistance, and oil resistance\u003c\/li\u003e\n  \u003cli\u003eRated torque of 1800 inch-pounds for demanding drive applications\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch minimum bore diameter, compatible with Series JE coupling size code 6\u003c\/li\u003e\n  \u003cli\u003e3.75 inch outside diameter and 1.88 inch overall length for precise fitment\u003c\/li\u003e\n  \u003cli\u003eOne piece solid sleeve design simplifies installation and replacement\u003c\/li\u003e\n  \u003cli\u003eAbsorbs shock loads and dampens torsional vibration to protect connected equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Series JE replacement sleeve insert for jaw-style flexible couplings with coupling size code 6 and a 5\/8 inch minimum bore diameter. Specific hub compatibility should be verified against LOVEJOY Series JE coupling documentation before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMillwrights or mechanical technicians typically install jaw coupling sleeve inserts during shaft alignment procedures or preventive maintenance. De-energize and lock out all power to the drive system before disassembling the coupling. Ensure both coupling hubs are clean and free of debris before seating the sleeve. Do not exceed the rated torque specification for this sleeve during operation, as overloading will accelerate wear or cause premature failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hytrel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: One Piece Solid Sleeve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Sleeve Insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: JE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size Code\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.88 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRated Torque\u003c\/strong\u003e: 1800 inch-pounds (203.37 N\/m)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: LOVEJOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 68514440738\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51541731836210,"sku":"68514440738","price":258.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/19663dcd28a7e5b49a9d410b37c8b0f5.jpg?v=1785883401","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514440738-flexible-sleeve-hytrel-5-8-in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
