Hi
This is my second post, including the welcome post :)
I have been reading the forums alot, especially the huge post the one user made to explain ballscrews. I can't find the URL now
I am designing a machine and I was wondering if the ballscrew shaft needs to sit flush with the BK bearing or is 1mm distance fine? I would prefer 1mm distance, because I don't know if the rest of the machine will be cut, from t-slot aluminium, as perfectly as the shaft
The pictures might explain better what I mean
In this image the shaft has been machined in the recommended way by the supplier. The shaft goes from 20mm down to 15mm down to 12mm. My question is, does the 20mm part of the shaft need to touch the bearing inside the housing?
