Lovejoy L110 Jaw Coupling Hub 32 mm Bore

SKU CH-AN5E-VFMSR

Jaw coupling hub with 32 mm bore and keyway, rated to 5,000 RPM and up to 3.6 hp at 100 RPM

  • 32 mm bore fits standard metric shafts
  • Carbon steel hub withstands 5 000 RPM operation
  • Buna-N spider delivers 1.3 hp at 100 RPM
  • Urethane spider provides 2 hp at 100 RPM
  • Hytrel spider supports 3.6 hp at 100 RPM

Jaw Coupling Hub with 32 mm Bore

This Lovejoy L110 hub is a carbon-steel jaw coupling component designed for metric shafting with a 32 mm round bore and a standard keyway. It suits maintenance technicians and OEM assemblers who need a straight-jaw hub for general-purpose power transmission up to 5,000 RPM.

Interchangeable Spider Options

The hub accepts L110N Buna-N, L110U urethane or L110H Hytrel centre elements, letting the installer choose damping, temperature range or torque capacity without changing the hub. At 100 RPM the Buna-N spider transmits 1.3 hp, urethane 2 hp and Hytrel 3.6 hp.

Set-Screw Locking on Carbon Steel

The carbon-steel hub uses a set-screw locking method on a 10 mm wide by 3.3 mm deep keyway, providing a secure mechanical connection for the 85 mm outside diameter and 107 mm overall length. The straight-jaw profile ensures straightforward alignment during installation.

Questions about this item

How often does the L110 spider element need replacement?

Replace the L110N, L110U or L110H centre element when visual inspection shows cracking, chunking or excessive wear; no fixed interval is defined for the coupling.

What limits continuous operation at the rated 5,000 RPM?

The 5,000 RPM ceiling is the maximum speed rating; sustained running at that speed is limited by the spider material’s heat capacity and the set-screw holding torque.

How much heat does the hub generate when running all day at 100 RPM under full load?

At 100 RPM the hub transmits up to 3.6 hp with a Hytrel spider; heat rise depends on alignment, lubrication and ambient temperature rather than a published figure.
