It mounts directly to a keyed shaft with a 5\/8 inch bore diameter and tight bore tolerances of +0.0005 inch to +0.0015 inch, ensuring a precise fit. The flange hub is machined from carbon steel and rated to a maximum speed of 9,200 RPM. A 4-way flexing action built into the sleeve insert absorbs shock, vibration, misalignment, and end float, protecting connected equipment from load spikes. Machinists, millwrights, and mechanical contractors install these flanges as part of a matched sleeve coupling assembly.\u003c\/p\u003e\u003cp\u003eThis coupling flange is suited for use in compressors, conveyors, motors, and pumps across industrial and commercial applications. It handles both angular and parallel misalignment, making it appropriate for drive trains where exact shaft alignment is difficult to maintain. The outside diameter measures 2-1\/16 inches with a 1-1\/2 inch hub diameter. Two set screws are included — one positioned over the keyseat and one at 90 degrees — securing the flange to the keyed shaft without additional fasteners. The part uses inch measurement standards and is manufactured in the USA.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFinished bore design mounts directly to 5\/8 inch keyed shafts with close tolerances\u003c\/li\u003e\n\u003cli\u003e4-way flexing sleeve action absorbs shock, vibration, angular misalignment, and parallel misalignment\u003c\/li\u003e\n\u003cli\u003eCarbon steel hub construction rated to 9,200 RPM maximum speed\u003c\/li\u003e\n\u003cli\u003eChemical resistant and oil resistant for demanding industrial environments\u003c\/li\u003e\n\u003cli\u003eIncludes two set screws: one over keyseat and one at 90 degrees for positive shaft retention\u003c\/li\u003e\n\u003cli\u003eScrew thread size 1\/4 inch-20 for standard tooling compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation flange for coupling size 3 sleeve coupling assemblies using inch-standard keyed shafts on compressors, conveyors, motors, and pumps.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified millwright or mechanical technician. Disconnect and lock out all power to the drive system before mounting or removing coupling components. Verify shaft keyway dimensions match the 1\/16 inch keyway width and 1\/8 inch keyway depth before pressing the flange onto the shaft. Pair this flange with the matching sleeve insert and opposite flange half to complete the coupling assembly; do not operate the coupling without the full matched set properly seated.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoupling Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 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\u003eOutside Diameter\u003c\/strong\u003e: 2-1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Body Length\u003c\/strong\u003e: 13\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Through Bore\u003c\/strong\u003e: 51\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeyway Width\u003c\/strong\u003e: 1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeyway Depth\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 9,200 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Material\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Type\u003c\/strong\u003e: Keyed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMisalignment Types\u003c\/strong\u003e: Angular; Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Hardware\u003c\/strong\u003e: 2 Set Screws (1\/4 inch-20)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-3J58\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TB WOODS","offers":[{"title":"Default Title","offer_id":51383056171314,"sku":"TB-3J58","price":34.55,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670415.jpg?v=1782586813","url":"https:\/\/voomisupply.com\/products\/tb-woods-tb-3j58-sleeve-coupling-flange-3-keyed-shaft","provider":"Voomi Supply","version":"1.0","type":"link"}
