I had a similar experience with Rockford & HiWin. HiWin's lead times were
long. I purchased ball screws from Rockford for my SuperMax (Bridgeport
copy) mill. Rockford had drawings for SuperMax retrofit ball screws which
I was able to buy. They were a little more expensive than Bridgeport
retrofit screws but fit right in. If you call Rockford you might ask about
your specific mill if it's not a Bridgeport.
