Speed Dial issues

I have a speed dial and so does my sister… But the problem is that both of our bearings have become about as smooth spinning as sand paper…

Has anyone else had this problem? And what can I do about it?

Thanx in advance.

Clean the bearing or put some thin lube in it. I think one of the ball bearings is loose but since it’s both or yours then it’s just the bearing needing lubrication or something. Won’t hurt to check though.
