Tiny bearings need no heating. SKF has a bearing installation guide book, it says on page 53, Cold mounting www.skf.com/binaries/pub12/Images/0901d1968013be94-SKF-bearing-maintenance-handbook---10001_1-EN(1)_tcm_12-463040.pdf "Mechanical methods Bearings with a cylindrical bore (d = max 80 mm) Small bearings should be mounted with an appropriate bearing fitting tool, e.g. the SKF Bearing fitting tool kit († fig. 14a)."
this is old comment and maybe too late too reply, I know by heat up bearing it can removed but some design, in my case the bearing was too close too rubber where the rubber cannot be removed. I think the goal of this video is not to remove bearing but how can we design so we can install and remove it easier.
