Thread: Putting Bearing on Drill
Threaded View

My pillar drill was worn out so I pulled all the bearings off and ordered new ones. However I note the bearings were really bloody tightly on there originally so I won't be able to put them back without using my bearing puller. Now I can do that for some of them but not all; one is right down the end of a long rod and the puller won't reach it.
I was wondering if they are put on with heat so the inner race of the bearing expands. What kind of temp could I heat the bearing to without worrying about melting the grease? 50C? It's a 6201-2RSH SKF bearing with plastic covers.
Is this the method they probably used when building the drill in the first place, or did they just use a lot of force?
EDIT: SKF induction heater has a standard temp of 110C, but they did not use a pre-greased bearing in the video.Last edited by Tenson; 26-10-2015 at 07:44 PM.
