Sure-Flex Sleeve Coupling Flange

The Tb Wood'S 3J58 is a flange hub designed for sleeve coupling assemblies in power transmission systems. It suits maintenance engineers and OEM builders fitting compressors, conveyors, motors or pumps where a keyed connection is required.

Build integration needs

The flange accepts a 5/8 inch round keyed bore with a tolerance of +0.0005 in to +0.0015 in and a hub body length of 13/32 in. It pairs with a matching sleeve to join shafts, freeing the drivetrain from rigid alignment constraints while transmitting torque through the elastomeric element.

Thermals noise and power

Carbon steel construction handles the rated 78 in-lb torque at speeds up to 9,200 RPM without active cooling. The metal hub runs silent and draws no power itself, so thermal management depends entirely on the driven equipment and the sleeve material selected.

Questions about this item

What is the maximum continuous speed before the coupling reaches its limit?

The coupling is rated for up to 9,200 RPM under sustained operation.

Does the carbon-steel flange generate noticeable heat or noise during all-day running?

As a solid metal flange without moving seals or bearings, it produces no audible noise and negligible heat on its own.

Which shaft diameter and keyway must already be on the driven equipment?

The flange fits a 5/8 in round keyed shaft with a bore tolerance of +0.0005 in to +0.0015 in.
