Re: [CAD_CAM_EDM_DRO] Need ballscrew support Bearings.

Scott,

Just a single DRAC bearing per axis is sufficient. On the X, only the driven side needs one. The other end of the screw just floats in a standard bearing. The bearings are a bit pricy, about 40 a piece. Standard endplate bearings being referenced.

Where is there a bearing thats 3.15" OD X 1.968" ID at on a Bridgeport series 1? Or is this a cutom set up? Or is this a Boss machine?

I need new ballscrew support bearings for both the X and Y axis. Big
question is if a matched set of the special "ballscrew support"
bearings are worth the extra money? (probably $400 per pair)

Will I really be able to notice a difference in performance if I just
use 2 "unmatched" angular contact bearings? Will they wear prematurely?

This is just a hobbiest machine and will not see heavy usage.
The bearings I need are:

Y- 52mm od, 25mm id, 15mm wide

Thanks for any help.
