## Customer Reviews

### ⭐⭐⭐⭐⭐ A Well-Made and Useful Stepper Ballscrew Mount
*by G***N on February 20, 2025*

This is a great adapter/jig for mounting and aligning a stepper motor to a ball screw. In my case, I'm converting a manual lathe to CNC, so this unit simplified the mounting of the motor driven end. Recommended

### ⭐⭐⭐⭐ Check your connection distance
*by J***R on November 25, 2025*

It’s well made but the distance between where the motor mounts and the bearing mounts doesn’t work and I had to come up with another option.

### ⭐⭐⭐⭐ Easy way to mount stepper motor and align with lead screw
*by D***K on January 22, 2025*

This is a great way to mount the stepper motors - makes the 'build your own' CNC much easier. Makes aligning the motor with the lead screw a no-brainer. Downside: expensive - cost more than the stepper motor. I first purchased a steel mount then discovered the same thing in aluminum which was much lighter which I liked.
