Sleeve Coupling Flange for 5J Systems

This Tb Wood'S 5J12 flange connects shafts in compressors, conveyors, motors and pumps. It accepts a 1/2 inch round keyed bore with a tolerance of +0.0005 in to +0.0015 in. The carbon steel hub measures 1 7/8 in diameter and 29/64 in body length. Rated for 312 in-lb maximum torque at up to 7,600 RPM.

Check Shaft Size and Keyway Before Ordering

Verify that your shaft diameter matches the 1/2 in bore and that the keyway suits a round keyed fit. Confirm the 3 1/4 in outside diameter clears adjacent components. The hub length through bore is 1 3/64 in, so ensure sufficient shaft engagement. No bushing is used with this flange hub design.

Steady Operation at Rated Torque and Speed

Under continuous load the coupling transmits up to 312 in-lb without exceeding its rating. The carbon steel hub resists wear during sustained running at speeds up to 7,600 RPM. Bore tolerance remains within +0.0005 in to +0.0015 in to maintain alignment. The fixed flange hub provides consistent torque transfer in compressor, conveyor, motor and pump applications.

Questions about this item

What is included with the 5J12 coupling flange and what else is needed to complete a coupling?

The flange ships as a single carbon-steel hub with a 1/2 in round keyed bore. A matching flange and a Sure-Flex sleeve must be purchased separately to form a working coupling.

How do I decide between the available bore sizes for the 5J flange?

Select the bore that matches your shaft diameter; this listing is the 1/2 in bore version, and other bore sizes are offered in the same 5J hub series.

What does the 7,600 RPM rating mean when the flange is mounted on a pump or compressor?

It is the maximum safe rotational speed for the complete coupling assembly; do not exceed 7,600 RPM in service.
