Cleaning Linear Bearings

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 . :grin:
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 .
