Of course you can remove the nut. You just roll it onto a correctly sized

In fact it's a good idea to do this with the linear slides and ballscrews
from china, to give them a wash. While they are greased up and wrapped in
plastic, they are often covered in grinding grit which won't help the
longevity of your drive system.


A trick I've used to clean a ballscrew and nut is to smear axle grease on the screw and run the nut across the greased region. You will get lots of unhappy noises. Then, wipe the grease off the screw, regrease and run the nut to the opposite end. Inspect the wiped off grease for sparkles, that is the ground-off steel that was trapped in the nut. Repeat until the crunching noises stop and you don't see the sparkles in the wiped-off grease. Then, you know it is pretty clean inside.

This is less nerve-wracking that taking it apart and wondering if it has alternate-sized balls or any other tricks in it.
