Lovejoy L110 19 mm Jaw Coupling Hub

SKU CH-A898-T4833

A jaw coupling hub with a 19 mm bore, 85 mm outside diameter and 107 mm overall length rated to 5,000 RPM

  • 19 mm bore fits metric shafts directly
  • Carbon steel hub withstands 5,000 RPM operation
  • 3 hp at 100 RPM with Buna-N spider
  • 6 hp at 100 RPM with Hytrel spider
  • Set-screw locking secures hub without extra hardware

Hub for 19 mm Shafts

This jaw coupling hub fits a 19 mm round bore with a 6 mm keyway and a 2.8 mm keyway depth. It is manufactured from carbon steel and uses a set-screw locking method to secure the hub to the shaft. The component is designed for metric power transmission systems requiring a Size L110 interface.

Carbon Steel Build and Set-Screw Mounting

The hub has an outside diameter of 85 mm and an overall length of 107 mm with a straight jaw profile. The set-screw locking provides a straightforward fastening method for maintenance or replacement tasks. Carbon steel construction delivers the mechanical strength needed for continuous industrial operation at the rated speeds.

Replaces Worn L110 Hubs in Existing Drives

This hub serves as a direct replacement for a damaged or worn Size L110 hub in established equipment. It accepts compatible center elements such as the L110H, L110N or L110U spiders to restore torque transmission. The upgrade is worth it when the original hub shows keyway wear or set-screw damage that compromises shaft grip.

The L110 hub is rated for 5 000 RPM maximum speed, which caps the rotational velocity of the connected shafts in operation.

What bore diameter and keyway dimensions does the L110 19 mm hub need to fit a shaft?

It fits a 19 mm round bore with a 6 mm keyway width and 2.8 mm keyway depth for positive torque transmission.

How is the L110 hub installed on the shaft, and what step is often missed?

Secure the set screw over the keyway after aligning the key; the step often missed is tightening the set screw to the specified torque value.
