Cleaning Linear Bearings

[Cadillac]

If you measure the balls they have what you’d need at McMaster Carr. They sell by the hundred and for the size it might be 10 dollars at most.

I have the ones that came out, it's just a PITA to take the machine apart to where I could put them back in. Plus, those little buggers really don't want to do anything you would like them to....

Doesn't seem to be hurting anything so I think I'll just leave it be for now.

So we have a bi-directional ball screw on some of our machines . The motor does not change direction but the carriage changes direction at a given point . I have not quite figured this out yet but I'm trying .

This sounds a lot like the level wind mechanism used on fishing reels. There is a groove with left and right hand lead on the shaft with the end of one lead connecting to the other. A key rides in the groove.https://www.youtube.com/watch?v=zv7cXR1UkWQ

Yes it is . We call it the cam screw . It has a ball screw with leads in both directions and the carriage rides on 4 linear bearings . We also wind filters on the other machines using similar mechanisms .
