Aluminium L-Jaw Hub, 1-1/4" Bore

The Lovejoy AL100114 is an L100-size jaw coupling hub machined from aluminium. It accepts a 1-1/4 inch round bore with a standard keyway and secures to the shaft with a set-screw. The hub is designed to mate with L100 urethane, Buna-N or Hytrel centre elements for power transmission up to 7 000 RPM.

Suits Light-Duty Inch-Shaft Drives

This hub fits builders assembling or repairing inch-dimension equipment that uses L100 jaw couplings and requires the corrosion resistance of aluminium. It is not for applications needing a larger bore, a clamp-style lock, metric shaft sizes or coupling sizes other than L100.

Verify Shaft Diameter and Keyway Before Order

Confirm the driven shaft measures exactly 1-1/4 inch diameter with a 1/4 inch wide by 1/8 inch deep keyway. Ensure the mating element carries an L100H, L100N or L100U part number and that the operating speed will not exceed the 7 000 RPM limit.

Questions about this item

What bore diameter and keyway dimensions must the shaft have to fit the AL100114 hub?

The hub accepts a 1-1/4 in round bore with a 1/4 in wide keyway and 1/8 in keyway depth.

Will the straight jaw profile of this L100 hub mesh with the spider elements I already use?

Yes, it is compatible with L100H, L100N and L100U center elements that share the straight jaw profile.

How can I confirm the hub is running within its rated limits after installation?

Verify the shaft speed does not exceed 7,000 RPM and that the transmitted horsepower at 100 RPM stays below the spider rating: 0.1 hp for urethane, 0.66 hp for Buna-N or 1.8 hp for Hytrel.
