Re: [CAD_CAM_EDM_DRO] Linear bearings - can someone help with how to reload?

Jeff: Since you are ALREADY panicked, guess it won't much ADD to your misery
to ask if you can REMOVE the ball-bushing in question — take it plumb-OFF the
shaft. Sometimes, that is just about the ONLY way you can get enough "play"
(aka "slop") between the ball-return groove and the hardened grooved bit of
steel the balls roll in. That bit of steel must obviously lift away from the
round-way JUST enough yo letcha push the balls in.

Things may "seem" to work even if you have several balls missing, but don't
forget, a relatively small % of the total # of balls are actually supporting
weight/force at any particular time, so if more than one or two are missing, the
"stress" on what's left will PROBABLY cause undue wear-rate, if not imminent
destruction.

I never saw ball-bushings with a HOLE into which one could push-in balls.
This Thomson stuff?

Lotsa luck! Jan Rowland
