Hi folks 
My SuperMAX knee mill is almost ready for new spindle bearings.
It has the Universal Quik-Switch 200 nose but is the same as a Bridgeport regarding the bearings.
I looked around a bit, but am wondering where you more experienced folks would normally go to purchase a set. 
New or refurbished ballscrews are next ..... if there's any $$$.$$ left in the kitty. 
Thanks for your time,
