  • 19 mm bore fits standard shafts
  • Carbon steel hub resists wear at 7 000 RPM
  • Set-screw locking secures the hub without extra parts
  • Accepts Buna-N, urethane or Hytrel spiders for torque choice
  • 64 mm diameter suits L100 coupling assemblies

Jaw Coupling Hub 19 mm bore

The Lovejoy L100 hub fits a 19 mm shaft with a standard keyway and set-screw locking. Carbon steel construction supports speeds up to 7,000 RPM and transmits up to 1.8 hp at 100 RPM with a Hytrel spider. Metric dimensions include a 64 mm outside diameter and 89 mm overall length. It is intended for general industrial power transmission.

Suits metric shafting with keyway

This hub serves maintenance teams replacing worn L100 couplings or OEMs building new drives on 19 mm shafts. It is not for applications that require a clamp or keyless locking method, nor for shafts larger than the stated bore. Buyers needing a different bore size or an inch-series hub should select another model.

Works with three spider types

The hub accepts Buna-N, urethane or Hytrel centre elements (part numbers L100H, L100N, L100U) so damping, torque capacity and temperature range can be matched to the application. Spiders are sold separately and must be ordered to complete the coupling assembly.

Questions about this item

What shaft diameter does the 19 mm bore of the L100 hub fit?

The hub has a 19 mm round bore with a 6 mm keyway and 2.8 mm keyway depth, so it fits a 19 mm shaft with a matching keyway.

Which spider materials can I use with the L100 hub I already have?

The L100 hub works with Buna-N (L100N), Urethane (L100U) and Hytrel (L100H) centre elements; horsepower at 100 RPM is .66 hp, 1 hp and 1.8 hp respectively.

How do I confirm the hub is running within its 7 000 RPM limit after installation?

Use a tachometer on the driven shaft; the reading must stay at or below 7 000 RPM during operation.
