Jaw Coupling Hub for 1-Inch Shafts

The TB Woods L1501 is a carbon-steel jaw coupling hub sized L150 with a 1-inch round bore and keyway. It uses a set-screw locking method and a straight jaw profile to connect rotating shafts in power-transmission systems. The hub accepts compatible centre elements including Buna-N, urethane and Hytrel spiders for different torque and damping requirements.

Suits Maintenance Teams Replacing Worn Hubs

Technicians servicing existing L150 couplings on inch-dimension equipment will find the correct bore size and keyway dimensions here. Builders who need a different bore diameter, a clamp-style hub or a metric-series coupling should look at other listings because this hub is fixed at 1 inch with a set-screw design.

Rated for Continuous Operation at 5,000 RPM

At 100 RPM the hub transmits 2 hp with a Buna-N spider, 3 hp with urethane and 5.9 hp with Hytrel, and the maximum speed rating is 5,000 RPM. These figures reflect steady-state capacity rather than momentary peak torque, so the coupling runs within its thermal and mechanical limits during extended duty cycles.

  • Set-screw locking secures the hub without extra hardware
  • Works with Buna-N, Urethane or Hytrel centre elements for flexible damping

Questions about this item

What shaft diameter and keyway does the L150 hub require?

The hub fits a 1 in round bore with a 1/4 in wide by 1/8 in deep keyway and uses a set screw for locking.

Can I keep my existing L150 Buna-N spider when installing this hub?

Yes, the hub is compatible with L150H Buna-N, L150N Urethane and L150U Hytrel centre elements.

How do I confirm the coupling is running within its rated limits?

Verify the shaft speed does not exceed 5,000 RPM and that the transmitted load stays below the spider’s horsepower rating at 100 RPM.
