Hi every one.
I have a G0704 CNC conversion and the spindle bearings need replacement. I have decided to go with Nachi tapered rollers this time. The angular contact bearings, I used during the first build had about 2 thou run out for some time now. I have seen the Nachi bearings being use in rebuilds and new conversions. So I have ordered the Nachi bearings. I have been trying to figure out preload and how to set it. I will be using Kluber lub and will be making a better top retaining nut to better load and keep preload consistent over the long haul. I have seen run out number in the mid tenths of a thou. I found the angular contacts to have a higher than I like maintenance need. Any help with this rebuild will be greatly appreciated.
Thanks for looking.
