I am looking at one of the many (similar, I assume) ballscrew kits on Ebay...I realize when they list the length, they are talking overall...I cannot find any dimensions of the motor mount end, where the threads are, and the coupler shaft go...
That is, an 800 mm screw, how long are the actual screw threads, and how long is each machined end? Trying to guage how long I need for my 750mm wide X axis
Thanks
