Tb Wood'S 5J1 Sure-Flex Sleeve Coupling Flange

This new Tb Wood'S 5J1 Sure-Flex sleeve coupling flange connects shafts on compressors, conveyors, motors and pumps. The flange hub accepts a 1 inch round keyed bore and transmits up to 312 in-lb of torque at speeds up to 7,600 RPM.

Installation notes

The flange hub is machined from carbon steel with a hub diameter of 1 7/8 in and a length through bore of 1 3/64 in. The bore tolerance is +0.0005 in to +0.0015 in, so the shaft must be sized within this range for a proper keyed fit.

Who this suits

This coupling suits maintenance teams replacing a worn 5J flange on existing inch-system equipment. Builders who need a different bore size, a metric bore or a complete coupling assembly with a flexible sleeve should look at other configurations.

Questions about this item

How can I verify the 5J1 Sure-Flex flange is running correctly after installation?

Confirm the shaft speed stays below 7 600 RPM and the driven load does not exceed 312 in-lb of torque; smooth, vibration-free rotation at operating speed indicates proper alignment and fit.

What components are included with the 5J1 flange and what must be purchased separately?

The package contains the carbon-steel flange hub with a 1 in round keyed bore; the mating flange, the flexible sleeve element, and any required key stock are sold separately.

Which bore tolerance should I select for a 1 in shaft on the 5J1 coupling?

The flange is manufactured to a +0.0005 in to +0.0015 in tolerance on the 1 in bore, providing a standard clearance fit for typical keyed shaft applications.
