Solid Choice

Works as expected for connecting my stepper motor to the lead screw. Just make sure you measure your shaft diameter correctly before ordering.

Durable Material

Stainless steel holds up well in my workshop environment. No signs of rust after a few months of use.

Good but tight

Quality is high but the fit was very tight on my 8mm shaft. Needed a bit of force to install, but once on it is very secure.

Excellent Rigidity

Used this for my CNC spindle setup. The stainless steel construction feels premium and there is absolutely no backlash. Highly recommend for precision applications.

Zero Backlash

Perfect for precision motion control. I replaced a flexible coupling with this rigid one and my accuracy improved significantly.
