Coupling hub for 18 mm shafts

The Lovejoy L100 jaw coupling hub fits an 18 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 L100 series centre elements including Buna-N, urethane and Hytrel spiders for torque transmission.

Thermal and power behaviour

At 100 RPM the hub transmits 0.66 hp with a Buna-N spider, 1 hp with a urethane spider and 1.8 hp with a Hytrel spider. Maximum rated speed is 7,000 RPM. No active cooling or lubrication is required during normal operation.

Bundled items and compatibility

The hub is supplied alone; centre elements L100H, L100N and L100U are purchased separately. Selecting the spider material changes the horsepower rating at a given speed. No software or additional hardware is included.

Questions about this item

How do I install the 18 mm bore hub on the shaft and which step is often missed?

Slide the hub onto the shaft, align the 6 mm keyway with the shaft key, then tighten the set screw over the key. The step often missed is placing the spider element between the two hubs before final tightening.

What maintenance or replacement will this hub need over time?

The hub itself is carbon steel and does not wear, but the compatible spider elements (L100N Buna-N, L100U Urethane, L100H Hytrel) are wear items and should be inspected and replaced when the jaws show excessive play or vibration.

At what speed limit does this L100 hub reach its maximum rating under sustained use?

The hub is rated for a maximum speed of 7,000 RPM; sustained operation at or above this speed is the first limit reached.
