I have a .001 backlash on ground ballscrews. The ball screw assembly is good and has no backlash. It is the bearing on the end. The bearing has a shoulder washer ( in hand) keeping it in place that uses shims to adjust the pressure on the bearing. I've adjusted out all the slop but .001. It seems the bearing is defective. I don't understand exactly how the bearing works and want to take it out to inspect it.
How do I remove the bearing for inspection? The bearing race fits loosely (it slides in and out) but the nut looks to be locktite in place. It appears that I should use an impact wrench and some special tool to remove the nut. Do I make the tool or is that a standard tool?
What else do I need to know?
This is a ballscrew from a Millpwr installation on a Bridgeport mill.
