  • Carbon-steel hub withstands 5,000 RPM continuous operation
  • 1-5/8 in bore with 3/8 in keyway fits standard shafts
  • Set-screw locking secures hub without additional hardware
  • Works with Buna-N, Urethane or Hytrel centre elements

Jaw Coupling Hub for 1-5/8 in Shafts

This Lovejoy L110 hub fits round shafts measuring 1-5/8 in bore with a 3/8 in keyway width and 3/16 in keyway depth. The carbon-steel body uses a set-screw locking method and straight jaw profile to connect driving and driven equipment in power-transmission assemblies.

Sustained Operation at Up to 5,000 RPM

Rated for continuous speeds up to 5,000 RPM, the hub transmits 1.3 hp at 100 RPM with a Buna-N spider, 2 hp with a urethane spider, and 3.6 hp with a Hytrel spider. The 3 21/64 in outside diameter and 4 15/64 in overall length provide the mechanical envelope for these power ratings under steady load.

Replaces Worn L110 Hubs

Use this hub to replace a damaged L110 unit or when stepping up from a smaller coupling size that can no longer handle the required torque. The jump is worth it when the application demands the L110 power ratings and the shaft diameter matches the 1-5/8 in bore exactly.

Questions about this item

How much heat and noise does the L110 hub generate when running continuously at 5,000 RPM?

The hub itself has no moving parts that produce heat or noise; any temperature rise or sound comes from the spider element and shaft alignment, not from the carbon-steel hub.

What shaft diameter and keyway dimensions must already be on the motor or driven shaft for this hub to fit?

The hub requires a 1 5/8 in round bore with a 3/8 in wide by 3/16 in deep keyway and uses a set-screw locking method.

Will this L110 hub work with the L110H, L110N and L110U centre elements I already have on older equipment?

Yes, the hub is compatible with all three spider part numbers — L110H (Hytrel), L110N (Buna-N) and L110U (Urethane) — so existing centre elements can be reused.
