I have a project where I use a threaded rod to allow a piece to move up and down the rod when rotated (much like a deodorant stick) now I need to fix the threaded rod to it's container in such a way that still allows the rod to rotate but not allow it to move any other way. My idea is to use a bearing between the rod and the container. The only way I can think to do so would be to weld the bearing to the rod. Is a simpler way or an already made piece of hardware to do this sort of thing?

    Don't weld bearings, you'll distort them and wreck the metallurgy of the races. Since it's threaded rod anyway, why not just put a nut above and below the bearing race and run them down to clamp it? Mill their edge down on a mill if they're too large diameter. Bonus points for Nyloks. – Harper - Reinstate Monica Jan 4 '19 at 2:32

Put a thrust bearing in the container and then, on the rod you can put a washer followed by two nuts. Tighten the nuts against each other so they don't move. Or maybe a nylock nut.

Assuming I'm understanding your question right.
