I just took out my room fan motor because it was starting to make a howling noise at the end of last winter. Looks to me like its the rear bearing. I think it seems to get hotter then the front one (closer to the cage) because the front one has a fan right next to it. So I pulled the bearing and starting looking on the net for one. It a "627s" and I can not seem to find one on the net. Does any one know how or where to get these bearings. Im hoping I don't have to buy a new blower! Plus if I do I fear it will do the same again. I was hoping to find a better replacement bearing. Any ideas guys?
