Coupling Hub for 1-1/2 in Shafts

This Lovejoy L150 jaw coupling hub fits a 1-1/2 in round bore with a 3/8 in keyway. It is made from carbon steel and uses a set-screw locking method. The hub is designed for power transmission applications up to 5,000 RPM.

Works with L150 Spiders for Upgraded Torque

The hub accepts L150H, L150N and L150U center elements. Horsepower at 100 RPM ranges from 2 hp with a Buna-N spider to 5.9 hp with a Hytrel spider. Choose the spider material that matches the torque and vibration requirements of the drive.

Verify Bore, Keyway and Speed Limits

Confirm the shaft diameter is exactly 1-1/2 in and the keyway measures 3/8 in wide by 3/16 in deep. Ensure the operating speed does not exceed 5,000 RPM. The hub uses set-screw locking, so check that this method suits the application.

Questions about this item

What shaft diameter and keyway dimensions does the L150 hub require?

The hub fits a 1 1/2 in round bore with a 3/8 in wide by 3/16 in deep keyway.

How is the hub secured to the shaft and which step is often missed?

Two set screws lock the hub; the step often missed is tightening both screws to the specified torque after aligning the key in the keyway.

Which centre element should be replaced and how often?

Replace the L150 Buna-N, Urethane or Hytrel spider when inspection shows cracks, chunking or excessive backlash; no fixed interval is defined.
