Lovejoy L-Jaw Coupling Hub L110 20 mm Bore

SKU CH-4PDG-R667K

Carbon-steel L110 hub with 20 mm bore and keyway fits L110 jaw coupling elements

  • 20 mm bore fits standard metric shafts
  • Carbon steel hub withstands 5 000 RPM operation
  • 85 mm outside diameter suits L110 jaw coupling size
  • 107 mm overall length matches standard coupling dimensions
  • Set screw locking secures hub to keyed shaft

Jaw coupling hub for 20 mm shafts

This Lovejoy L110 hub fits a 20 mm round bore with a 6 mm keyway and 2.8 mm keyway depth. It is made from carbon steel and uses a set-screw locking method. The hub accepts L110H, L110N or L110U centre elements for power transmission applications.

Simple set-screw mounting on metric shafts

Slide the hub onto the prepared shaft, align the key with the 6 mm keyway and tighten the set screw to secure it. The straight jaw profile ensures the spider seats squarely; misalignment or an undersized key are the typical causes of vibration or premature wear.

Suits metric shafting up to 5 000 rpm

Builders needing a 20 mm bore hub rated for 1.3 hp at 100 rpm with Buna-N, 2 hp with urethane or 3.6 hp with Hytrel spiders will find this hub matches the spec. It does not suit shafts without a keyway, imperial bores or speeds above the rated maximum.

Questions about this item

How can I confirm the hub is running correctly after installation?

Verify smooth rotation at up to 5,000 RPM with no vibration or noise and ensure the set screws remain tight on the 20 mm keyed shaft.

What components are included and what must I purchase separately?

The L110 hub with 20 mm bore, 6 mm keyway and set screws is supplied; you must buy a compatible spider such as L110N Buna-N, L110U Urethane or L110H Hytrel separately.

Which spider material should I choose for my power requirement?

Select Buna-N for 1.3 hp at 100 RPM, Urethane for 2 hp or Hytrel for 3.6 hp at the same speed.
