Couple your shafts or lead screws with this one piece 1/2" (12.7mm) to 1/4" (6.35mm) flexible clamping coupling. These flexible couplings will allow a bit of misalignment.

These hubs will typically be used on motors with 3/8" shafts.

Generally, the motor shaft with a 1/4" diameter will be inserted in one end, and a shaft, or lead screw measuring 1/2" in diameter will be inserted into the other end or vice versa.

Generally, the motor shaft with a 1/2" diameter will be inserted in one end, and a shaft, or lead screw measuring 3/4" in diameter will be inserted into the other end or vice versa.

Generally, the motor shaft with a 1/2" diameter will be inserted in one end, and a shaft, or lead screw also measuring 1/2" in diameter will be inserted into the other end. The screws that clamp the shafts will be tightened. These steel clamping coupling are for use with high torque motors and high inertia when the motor is changing directions.

Rigid couplings will keep backlash to a minimum, since the coupling is one single piece.

Generally, the motor shaft with a 14mm diameter will be inserted in one end, and a shaft, or lead screw also measuring 1/2" in diameter will be inserted into the other end. The screws that clamp the shafts will be tightened. These steel clamping coupling are for use with high torque motors and high inertia when the motor is changing directions.

With this coupling, the motor shaft with a 1/2" diameter will be inserted in one end, and a shaft, or lead screw also measuring 1/4" in diameter, or vice versa, will be inserted into the other end.

Rigid couplings will keep backlash to a minimum, since the coupling is one single piece. Generally, the motor shaft with a 1/4" diameter will be inserted in one end, and a shaft, or lead screw also measuring 1/4" in diameter will be inserted into the other end. The screws that clamp the shafts will be tightened, but not too much. These types of clamping couplings will not damage the shafts.

This hub is typical used to fasten to a 1/2" lead screw.

These hubs will typically be used on motors with 3/8" shafts.

This hub can be fastened to a 1/4" motor shaft or a 1/4" lead screw.

If you have a 5/8" lead screw, this is the hub for you.

This is the middle section of the coupling set. You will only need one of these to complete a set for one motor and one lead screw.

This hub can be fastened to a 1/4" motor shaft or a 1/4" lead screw.
