Jaw Coupling Hub 24 mm Bore

The Lovejoy L100 hub is a carbon-steel jaw coupling component with a 24 mm round bore and keyway. It connects two shafts in power-transmission systems using a compatible elastomer spider. The hub suits metric-dimension machinery where a straight-jaw profile and set-screw locking are specified.

Fits L100 Coupling Assemblies

This hub accepts centre elements with part numbers L100H, L100N or L100U and requires a matching hub on the opposite shaft. The set-screw locking secures the hub to a keyed shaft, while the straight jaw profile engages the spider to transmit torque. No additional clamping hardware is needed beyond the supplied set screw.

Torque Capacity at 100 RPM

With a Buna-N spider the hub transmits 0.66 hp, with urethane 1 hp and with Hytrel 1.8 hp at 100 rpm. Maximum rotational speed is 7,000 rpm. The 64 mm outside diameter and 89 mm overall length define the space envelope. Applications demanding higher horsepower or speed ratings will require a larger coupling size.
