i have purchased some warner electric 3/8 inch ballscrews and nuts and am trying to figure out a way to mount them in my mini mill without extensive mods to the mill(mainly because i dont have anything else to machine it with!)
im wondering if i need to use thrust bearings or if i can use good quality precision bearings if held firmly on both sides?
i mean, how much axial force is really going to be put on the bearings with a mini mill anyway?
i ask this because finding thrust bearings to fit this ballscrew after machining the ends down to 5/16ths or so is impossible. i can find precision bearings all over the place that would fit snuggly on the ends. and i think that if i enclose the bearings just down to the ballscrew, with the motor mounting plate on both sides that this would work.

any ideas or suggestions from you fellow CNC'ers or knowlegable people out there??
thank s for the input if any
