Machined from cast iron, this flange hub mounts directly onto a keyed round bore shaft with a 5\/8-inch bore diameter and bore tolerance of +0.0005 to +0.0015 inches. It pairs with a matched sleeve insert to complete the coupling assembly, accommodating both angular and parallel misalignment. The 4-inch outside diameter hub is rated to 6,000 RPM maximum speed. Two set screws are included, positioned one over the keyseat and one at 90 degrees, securing the flange firmly to the shaft. Licensed HVAC, mechanical, and industrial technicians install this component as part of power transmission assemblies.\u003c\/p\u003e\n\u003cp\u003eThe TB-6J58 flange hub is suited for use in compressors, conveyors, motors, and pumps across residential and commercial mechanical systems. The 4-way flexing action of the mating sleeve insert absorbs shock loads, misalignment, and end float, reducing stress on connected shaft components. Chemical-resistant and oil-resistant properties make this flange appropriate for environments where fluid exposure is common, such as pump rooms and mechanical equipment rooms. It ships as a single flange hub with two set screws and requires a compatible TB WOODS sleeve insert to complete the coupling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCast iron construction provides durability in industrial and commercial drive applications\u003c\/li\u003e\n  \u003cli\u003eFinished bore at 5\/8 inch with close tolerance fit for keyed round shafts\u003c\/li\u003e\n  \u003cli\u003eRated to 6,000 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eAccommodates angular and parallel shaft misalignment via mating sleeve insert\u003c\/li\u003e\n  \u003cli\u003eChemical-resistant and oil-resistant for wet or fluid-exposed environments\u003c\/li\u003e\n  \u003cli\u003eIncludes two set screws: one over keyseat, one at 90 degrees for secure shaft retention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with keyed round bore shafts, size 6 TB WOODS sleeve coupling assemblies.

De-energize all connected motors and lock out power before mounting or removing coupling flanges per OSHA lockout\/tagout procedures. Verify shaft diameter, keyway dimensions, and bore tolerance before pressing the flange onto the shaft. Do not operate the coupling without the mating sleeve insert properly seated between both flanges.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 6,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Tolerance\u003c\/strong\u003e: +0.0005 in \/ +0.0015 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Type\u003c\/strong\u003e: Round Keyed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Width\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Depth\u003c\/strong\u003e: 3\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Through Bore\u003c\/strong\u003e: 1-5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Body Length\u003c\/strong\u003e: 9\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Type\u003c\/strong\u003e: Flange Hub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Thread Size\u003c\/strong\u003e: 5\/16 inch-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Hardware\u003c\/strong\u003e: 2 Set Screws\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMisalignment Types\u003c\/strong\u003e: Angular, Parallel\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: 1.2 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-6J58\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TB WOODS","offers":[{"title":"Default Title","offer_id":51383884349746,"sku":"TB-6J58","price":64.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670351.jpg?v=1782610584","url":"https:\/\/voomisupply.com\/products\/tb-woods-tb-6j58-sleeve-coupling-flange-4-in-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
