Troubleshooting: Ballscrew or Thrust Bearings?

Is your ballscrew bad or just the thrust bearings?

Here's a quick check:

  1. Remove the left side X axis waycover
  2. Remove the bottom cover to expose the end of the ballscrew
  3. Place a mag base and indicator on the saddle
  4. Indicate off the end of the ballscrew, and zero using a .0001" indicator
  5. Turn the ballscrew 45 degrees or so and does it move or than .0003"
  • Yes:  Bad thrust bearings
  • No:  Loose gibs or bad ballscrew

Now double check yourself.  Reach under the table with the control in E-Stop mode and turn the ballscrew by hand.  Is it smooth or rough?  It should not be rough at all, but you could be feeling the thrust bearings, so you will need to remove the ballnut bolts so you can turn it alone by hand to see if it is gritty.  If so, or it is loose and sloppy feeling, replace the ballscrew.

We stock all machine models's ballscrews from the late 1980's through 2008 so give us a call whether you need bearings and seals or just a ballscrew.  208-888-9236
