Industrial Coupling Flange for 1-1/4 Inch Shafts

The Tb Wood'S 6J114 Sure-Flex sleeve coupling flange fits a 1-1/4 inch round keyed bore with a tolerance of +0.0005 in / +0.0015 in. It is rated for 6,000 RPM maximum speed and 585 in-lb maximum torque. This cast iron flange hub suits compressors, conveyors, motors and pumps.

Cast Iron Hub with 4 Inch Outside Diameter

The flange hub measures 4 inches outside diameter and 2-1/2 inches hub diameter with a 9/16 inch body length. Length through bore is 1-5/16 inches. Cast iron construction handles shock loads in power transmission drives. No bushing is required for this direct bore mounting.

Replaces Worn Sure-Flex 6J Flanges on Existing

This new flange replaces a damaged or worn 6J coupling half without changing the sleeve or the mating hub. The upgrade is worth it when vibration, keyway wear or bore damage degrades alignment. Buyers needing a different bore size or a complete coupling assembly cannot use this single flange alone.
