Lovejoy

Lovejoy L1001 Jaw Coupling Hub L100 1 in Bore

SKU CH-D1N4-K1D5J

Carbon steel jaw coupling hub with 1 inch bore and keyway for power transmission up to 7,000 RPM

  • 1 in bore fits standard shafts
  • Carbon steel hub handles 7,000 RPM
  • Set-screw locking secures the hub
  • Works with Buna-N, Urethane or Hytrel spiders
  • Keyway 1/4 in wide by 1/8 in deep

Jaw Coupling Hub L100 1 in Bore

The Lovejoy L1001 jaw coupling hub fits a 1 in round bore with a 1/4 in keyway and 1/8 in keyway depth. It is made from carbon steel and rated for 7,000 RPM maximum speed. This component is for maintenance teams and OEM builders assembling or repairing inch-system power-transmission drives.

Compatible Buna-N Urethane Hytrel Spiders

The hub accepts L100H Buna-N, L100N Urethane and L100U Hytrel centre elements, which change the torque rating at 100 RPM to 0.66 hp, 1 hp and 1.8 hp respectively. Selecting the spider material lets the installer match vibration damping, misalignment capacity and chemical resistance to the application.

Suits Inch Shaft Repairs Not Metric

This hub suits technicians replacing a worn L100 hub on 1 in keyed shafts. It does not suit metric bores, keyless clamping or applications needing a different coupling size. Buyers who need another bore diameter or a non-set-screw locking method should look at other hubs.

Highlights

  • 1 in bore fits standard shafts
  • Carbon steel hub handles 7,000 RPM
  • Set-screw locking secures the hub
  • Works with Buna-N, Urethane or Hytrel spiders
  • Keyway 1/4 in wide by 1/8 in deep

Questions about this item

Will the 1 in bore with 1/4 in keyway and set-screw locking need periodic re-torquing?

The set-screw shaft locking on the 1 in round bore with 1/4 in keyway should be checked and re-torqued at regular maintenance intervals to maintain secure hub-to-shaft connection.

What limits continuous operation at the 7,000 RPM maximum speed?

The 7,000 RPM rating is the maximum speed limit; sustained operation at this speed requires proper alignment and a compatible spider to avoid premature wear or vibration.

How much heat does the carbon-steel hub generate when running all day at 1 hp with a urethane spider?

The carbon-steel hub itself generates minimal heat; temperature rise comes mainly from the urethane spider transmitting 1 hp at 100 RPM, so ensure adequate ventilation around the coupling.
