I had a question how the BK15 and the Ball screw how are mounted together, i know there is a lock nut at the other end, but how flush is the ball screw with the surface in blue in the attachment. The BK15 was drawing per dimensions i got from the internet, there are no indications of how far inside the bearing is or if it is flush with that surface (in blue). after I figure this out I can go ahead and order form linearmotionbearing2008.
