L100 Jaw Coupling Hub

The Lovejoy L100 hub fits a 14 mm round bore with a 5 mm keyway and 2.3 mm keyway depth. It is made from carbon steel and uses a set-screw locking method. The hub accepts L100H, L100N or L100U centre elements for power transmission applications.

Build and Mounting Details

The outside diameter is 64 mm and the overall length is 89 mm. A straight jaw profile engages the spider element directly. The metric bore and keyway dimensions suit standard shafting in machinery and machine-shop equipment.

Speed and Power Ratings

Maximum speed is 7,000 RPM. At 100 RPM the hub transmits 0.66 hp with a Buna-N spider, 1 hp with a urethane spider and 1.8 hp with a Hytrel spider. These ratings let engineers match the hub to the required torque and speed envelope.

Questions about this item

Does the L100 hub's 14 mm bore with 5 mm keyway fit my 14 mm shaft?

The hub has a 14 mm round bore with a 5 mm wide by 2.3 mm deep keyway, so it matches a 14 mm shaft that has a standard 5 mm keyway.

What centre-to-centre distance does the 89 mm overall length require?

The hub is 89 mm long overall; with two hubs and a spider the centre distance equals 89 mm plus the spider thickness.

How do I install the set-screw hub without stripping the screw?

Align the hub keyway with the shaft key, slide the hub on, then tighten the set screw against the key — not the bare shaft — to avoid damage.
