Carbon steel jaw coupling hub L100 15mm bore 64mm OD 89mm length

Lovejoy

Lovejoy L100 Jaw Coupling Hub 15mm Bore 64mm OD 89mm Length

SKU CH-H0XD-7K603

Carbon-steel jaw coupling hub with 15 mm bore, 64 mm OD and 89 mm length for L100 spiders rated to 7 000 RPM

  • Ready for 7,000 RPM operation with carbon steel hub
  • 15 mm round bore with 5 mm keyway for secure shaft fit
  • Set screw locking simplifies installation and alignment
  • Compatible with Buna-N, urethane and Hytrel centre elements
  • 64 mm outside diameter and 89 mm overall length fit L100 couplings

Coupling Hub L100 15mm Bore

This Lovejoy jaw coupling hub fits a 15 mm shaft with a 5 mm keyway and 2.3 mm keyway depth. The carbon-steel hub has a 64 mm outside diameter and an 89 mm overall length. It uses a set-screw locking method and accepts L100 Buna-N, urethane or Hytrel center elements.

Verify Shaft and Element Before Ordering

Confirm the driven shaft measures exactly 15 mm and provides a 5 mm keyway at 2.3 mm depth. Ensure the mating hub uses the same L100 jaw profile and that the center element material matches the torque requirement. The hub is rated for 7,000 RPM maximum speed.

Replaces Worn L100 Hubs on Existing Drives

This hub directly replaces a damaged or worn L100 coupling hub without changing the spider or the opposite hub. The upgrade is worth it when the current hub shows keyway wear, set-screw damage or corrosion that compromises torque transmission at up to 1 hp with urethane or 1.8 hp with Hytrel spiders at 100 RPM.

Highlights

  • Ready for 7,000 RPM operation with carbon steel hub
  • 15 mm round bore with 5 mm keyway for secure shaft fit
  • Set screw locking simplifies installation and alignment
  • Compatible with Buna-N, urethane and Hytrel centre elements
  • 64 mm outside diameter and 89 mm overall length fit L100 couplings

Questions about this item

What comes in the box with the L100 hub and what must I buy separately?

The box contains one carbon-steel jaw coupling hub with a 15 mm round bore and 5 mm keyway. You must purchase a compatible spider element (L100H Buna-N, L100N Urethane or L100U Hytrel) separately to complete the coupling.

Which spider element should I choose for the L100 hub — Buna-N, Urethane or Hytrel?

Choose Buna-N (L100H) for general purpose at 0.66 hp per 100 RPM, Urethane (L100N) for higher torque at 1 hp per 100 RPM, or Hytrel (L100U) for maximum capacity at 1.8 hp per 100 RPM.

What does the 7,000 RPM maximum speed mean when the hub is installed on a 15 mm shaft?

The 7,000 RPM rating is the hub's mechanical speed limit; actual operating speed must also respect the spider element's rating and the shaft/keyway connection's torque capacity.
