Motor Mounting Bracket and BK12 Bearing End Support Block for Nema 23 Stepper Motor and Ball Screw 16mm Ballscrew SFU1604 SFU1605 SFU1610 as CNC Kit Parts

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.

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

This is an awesome adapter but the coupler to ball screw needs to be longer (40mm) and it’s made to go on the very end of table so if you mount it further up on the table then you need a wood shim to make it level. I would still buy this again.

I just needed something to hold a NEMA 23 motor on my desk for testing some brushless controller evaluation boards and field oriented control firmware. The aluminum was shipped dirty or coated with something which has soiled up some of my other stuff since I was not expecting this with aluminum and was handling it in areas I apparently should not have. I would have been more cautious with steel items... The bearings and sleeves did not appear to have this coating on them. I also needed to chase a tap through the threads so M4 screws would thread in smoothly. I'm not sure if the coating was clogging the threads, but I suspect it at this point.
