Excellent torque transmission
Using this for a stepper motor setup. It handles the torque well without flexing too much. Very satisfied with the performance.

Precise keyway cut
The keyway option was machined precisely. Made installation on the lead screw very straightforward. Highly recommend for precision applications.

Perfect for my CNC project
Fit perfectly on my NEMA 23 motor. The aluminum alloy feels very durable and the anodizing is smooth. No backlash noticed during testing.

Reliable component
Works well with lead screws. Noticed slight vibration at max speed, but within normal range for this type of coupling. Good value.
Q: Where does this product ship from?
A: All units are manufactured and shipped directly from our facility in Dongguan, Guangdong.
Q: Does this coupling fit a NEMA 17 motor shaft?
A: Yes, provided you select the appropriate bore diameter variant that matches the 5mm shaft of the NEMA 17 motor.
Q: What is the maximum RPM this can handle safely?
