  • 45 mm bore fits metric shafts directly
  • 127 mm outside diameter suits L225 coupling size
  • 7 hp at 100 RPM with Buna-N spider
  • 4,600 RPM maximum speed for high-speed drives
  • Set-screw locking secures hub to keyed shaft

L225 Jaw Coupling Hub 45 mm Bore

This cast-iron hub is a metric L225 jaw coupling component with a 45 mm round bore and keyway. It uses a set-screw locking method and straight jaw profile to connect rotating shafts in industrial power-transmission systems.

Verify Shaft Diameter Keyway and Speed Limit

Confirm the driven shaft measures 45 mm and matches the 14 mm keyway width and 3.8 mm keyway depth. Ensure the application does not exceed 4 600 RPM and select a compatible spider material for the required horsepower at 100 RPM.

Pair With L190 Spider Elements

The hub accepts L190 Buna-N, urethane or Hytrel center elements to complete the coupling. Cast-iron construction handles the rated torque while the set-screw fixation avoids additional clamping hardware. No other coupling sizes or spider series are compatible with this hub.

Questions about this item

Does the L225 hub arrive with a spider or must the Buna-N, Urethane or Hytrel element be ordered separately?

The hub is sold alone; the centre element (L190H, L190N or L190U) is not included and must be purchased separately.

Which spider material should I select for the 45 mm bore hub running at 100 RPM?

At 100 RPM the Buna-N spider delivers 3.7 hp, the Urethane spider 5.6 hp and the Hytrel spider 9.9 hp — choose the rating that meets your torque requirement.

What does the 4,600 RPM limit mean for continuous operation on a 45 mm shaft?

4,600 RPM is the maximum safe speed for the cast-iron hub; running above it risks mechanical failure regardless of the spider fitted.
