Fantastic! I had a difficult time finding a hub that would work with my stepper motor.

fits RB-Sct-417 wheels
I'm using this hub with Actobotics 4" Heavy Duty Wheel (RB-Sct-417) which fits perfectly. Just be aware neither the wheel or the hub comes with necessary screws. I had to make a stop at a local Lowes. They fit perfect to my NEMA 17 stepper with 5mm shaft.
