Lovejoy L110 Jaw Coupling Hub 3/4 in

The Lovejoy L110 jaw coupling hub fits a 3/4 inch round bore with a standard keyway. It is made from carbon steel and uses a set-screw locking method to secure the hub to a shaft. This hub is designed for power transmission applications requiring a straight jaw profile.

Practical limits of the L110 interface

The hub accepts L110H, L110N and L110U centre elements which determine the torque and vibration characteristics. Maximum speed is rated at 5,000 RPM and horsepower at 100 RPM ranges from 1.3 hp with a Buna-N spider to 3.6 hp with a Hytrel spider. The overall length is 4 15/64 inches and the outside diameter is 3 21/64 inches.

Check your existing setup before ordering

Verify that your shaft diameter is exactly 3/4 inch and that the keyway dimensions match the 3/16 inch width and 3/32 inch depth. Confirm the required centre element material for your torque and misalignment needs. Ensure the 5,000 RPM speed limit and the hub's physical envelope suit the available space.

Questions about this item

Should I choose the Buna-N, Urethane, or Hytrel spider for this L110 hub?

The hub works with L110H (Hytrel), L110N (Buna-N), or L110U (Urethane) spiders. At 100 RPM the Hytrel element delivers 3.6 hp, Urethane 2 hp, and Buna-N 1.3 hp.

What does the 5,000 RPM rating mean once the hub is installed on a 3/4 in shaft?

5,000 RPM is the maximum safe speed for the L110 hub with a 3/4 in bore and keyway. Exceeding it risks hub or spider failure.

Does the set-screw locking on this 3/4 in bore hub limit torque compared to a clamp style?

The set-screw hub transmits torque through the keyway (3/16 in wide, 3/32 in deep) and screw friction. Spider choice sets the hp limit: 1.3 hp Buna-N, 2 hp Urethane, 3.6 hp Hytrel at 100 RPM.
