L225 50 mm jaw coupling hub

This cast iron hub fits a 50 mm shaft with a 14 mm keyway and set screw locking. It is built for metric drivetrains that use straight jaw profiles and standard L190 centre elements.

Torque capacity by spider material

At 100 RPM the hub transmits 3.7 hp with a Buna-N spider, 5.6 hp with urethane and 9.9 hp with Hytrel. Maximum rated speed is 4 600 RPM, so high speed or shock loads will run out of headroom before the hub itself does.

Cast iron construction and mounting

The 127 mm outside diameter and 137 mm overall length keep the assembly compact. Set screw locking on a round bore with keyway gives simple alignment but requires periodic re torque on reversing or vibrating drives.

  • Cast iron hub withstands heavy-duty torque loads

Questions about this item

Will the L225 hub with its 50 mm bore and 14 mm keyway fit the motor shaft I am keeping?

The hub has a 50 mm round bore with a 14 mm wide by 3.8 mm deep keyway, so it matches any shaft with those exact dimensions.

How can I confirm the L225 hub is running correctly once installed?

At 100 RPM the assembly should deliver 3.7 hp with a Buna-N spider, 5.6 hp with urethane, or 9.9 hp with Hytrel without exceeding 4 600 RPM.

Does the box include the L190 spider or must I order it separately?

Only the cast-iron hub is supplied; a compatible L190H, L190N or L190U centre element must be purchased separately.
