This component connects a drive shaft to a mating coupler half, transmitting torque between a motor and driven equipment. The 4J jaw configuration pairs with a standard spider insert, and the 1\/2-inch bore accommodates common motor and pump shaft sizes. It is installed by millwrights, HVAC technicians, and equipment service professionals in mechanical drive train applications where vibration dampening and misalignment tolerance are required.\u003c\/p\u003e\n\u003cp\u003eThis coupler end is suited for light-duty to medium-duty rotating equipment commonly found in HVAC systems, pumps, blowers, and general industrial machinery. The 4J jaw size fits within the standard Woods coupling family, making it a straightforward replacement component in existing coupling assemblies. It is appropriate for both residential and light commercial mechanical equipment installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4J jaw configuration compatible with standard Woods-style flexible jaw coupling assemblies\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch bore fits common motor and pump shaft diameters\u003c\/li\u003e\n  \u003cli\u003eDesigned to transmit torque while accommodating minor shaft misalignment\u003c\/li\u003e\n  \u003cli\u003eDrop-in replacement style for existing 4J coupling installations\u003c\/li\u003e\n  \u003cli\u003ePaired with a separate spider insert to complete the flexible coupling connection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement coupler end for flexible jaw coupling assemblies using the 4J jaw size and a 1\/2-inch bore shaft.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a qualified millwright, HVAC technician, or mechanical equipment service professional. Always de-energize and lock out the motor or drive unit before servicing any coupling component. Ensure the shaft and bore are clean and free of burrs before seating the coupler end, and verify that the mating coupler half and spider insert are in serviceable condition before reassembly. Refer to the equipment manufacturer's service documentation for shaft key and setscrew requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Size\u003c\/strong\u003e: 4J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Style\u003c\/strong\u003e: Woods flexible jaw coupler end\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: CROWN ENGINEERING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 41906\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CROWN ENGINEERING","offers":[{"title":"Default Title","offer_id":51468209914162,"sku":"41906","price":36.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/WoodsJSeriesCoupling_90abdb92-0172-4fe1-becc-96dc30677b0b.jpg?v=1783914552","url":"https:\/\/voomisupply.com\/products\/crown-engineering-41906-woods-coupler-end-4j","provider":"Voomi Supply","version":"1.0","type":"link"}
