ballscrew to stepper shaft alignment

[marbles]

There is nothing wrong with the BK-type housing, it's the correct component for the job, it's just that the cheap ones come with crappy bearings. So just replace the bearings with angular contact bearings.

This will be much simpler than making plates and fitting bearings into them because if you don't bore the opposing bearing pockets perfectly concentric to each other then you'll introduce more issues.!

Cheers Dean, will get on it and order up a set. I've got 1605 ballscrews so prob 7201-2rs as dazp1976 says

The 7201 have a 32mm od. (32xx12x10mm).
I think the BK blocks take a 28mm od bearing. 28x12x9mm if memory serves correct.

I chose to custom mine to fit the 7201 just for a little more strength.
