Tb Wood'S 6J34 Sure-Flex Sleeve Coupling Flange 6J Bore 3/4 in

SKU CH-HG9W-37BE7

Connects shafts in compressors, conveyors, motors and pumps with a 3/4 in bore and 585 in-lb torque capacity

  • Transmits up to 585 in-lb torque for reliable power transfer
  • Operates at speeds up to 6,000 RPM for high-speed applications
  • Precision bore tolerance of +.0005 / +.0015 in ensures accurate shaft fit
  • Cast iron hub provides durability in demanding industrial environments
  • 3/4 in keyed bore fits standard shaft sizes for easy installation

Coupling Flange for 3/4 in Bore

The Tb Wood'S 6J34 Sure-Flex sleeve coupling flange fits a 3/4 inch round keyed bore. It connects shafts on compressors, conveyors, motors and pumps. The cast iron hub measures 2 1/2 inches in diameter and the flange has a 4 inch outside diameter.

Upgrade From Worn or Undersized Flanges

Replace a flange when the keyway shows wear or when the hub diameter no longer matches the shaft. The jump is worth it if the current part cannot handle 585 in-lb of torque or 6,000 RPM. The bore tolerance of +0.0005 in to +0.0015 in ensures a precise fit on standard shafts.

Steady Operation at Rated Limits

Under continuous load the flange transmits up to 585 in-lb without exceeding its design limits. The 9/16 inch hub body length and 1 5/16 inch length through bore keep the assembly rigid at speeds up to 6,000 RPM. It is not for applications that exceed these torque or speed ratings.

Questions about this item

What shaft size fits the 3/4 in bore and +0.0005 in / +0.0015 in tolerance?

A 3/4 in shaft within the +0.0005 in to +0.0015 in over-size tolerance fits the round keyed bore of this flange.

How do I install the 6J34 flange on the shaft and what step is often missed?

Slide the flange onto the shaft, align the key with the keyway, then tighten the set screw over the key; the missed step is verifying the key seats fully before locking the screw.

When should the Sure-Flex sleeve be replaced on this 6J coupling?

Replace the sleeve when visual inspection shows cracking, chunking, or excessive wear that would let the flanges contact beyond the 585 in-lb torque rating.
