View Full Version : Shrink Fits

07-27-2003, 04:11 PM
A little while ago I replaced the bearings on my wood lathe. The fit was quite tight and since I don't have a press I thought that I would just heat up the bearing and freeze the shaft. Well, the bearing slipped on nicely and everthing is running fine, but there was some condensation on the shaft after it warmed back up. Now I'm wondering if the bearing and shaft will rust together. I can't see myself needing to change the bearings for at least 20 years if not more, so this isn't really an issue for me; however, in situations where shrink fitted parts may need to be dissasembled in the future, is this a problem and how is it avoided.

if the bearing went on warm/hot (<<250*F) it would drive the moisture off. Don't sweat it (pardon the pun) - should be fine
