L150 Jaw Coupling Hub 48 mm Bore

The Lovejoy L150 jaw coupling hub is a carbon-steel power-transmission component with a 48 mm round bore and standard keyway. It connects two shafts in metric machinery using a straight-jaw profile and set-screw locking, rated to 5,000 RPM maximum speed.

Fits L150 Buna-N, Urethane or Hytrel Spiders

This hub accepts L150H, L150N or L150U centre elements, delivering 2 hp at 100 RPM with Buna-N, 3 hp with Urethane or 5.9 hp with Hytrel spiders. It is not for applications requiring a different coupling size, a clamp or keyless hub, or speeds above the rated limit.

Set-Screw Mounting on Keyed Shafts

Installation uses the integral set screw over a 14 mm wide by 3.3 mm deep keyway; the hub overall length is 114 mm and outside diameter 95 mm. Common issues are incorrect key fit or over-tightening the set screw, which can distort the bore.

Questions about this item

What shaft diameter and keyway dimensions must my motor or driven shaft have to fit the 48 mm bore?

The hub accepts a 48 mm round shaft with a 14 mm wide by 3.3 mm deep keyway and locks with set screws.

Will the L150 hub mate with Buna-N, Urethane or Hytrel spiders I already have on other L150 couplings?

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

How can I confirm the coupling is running correctly after installation?

Verify smooth rotation up to 5,000 RPM, check that transmitted torque matches the 2 hp Buna-N, 3 hp Urethane or 5.9 hp Hytrel ratings at 100 RPM, and inspect for vibration or unusual noise.
