would somebody please post on here how to service vacuum cleaner bearings. So we can print the instructions out.. It would be a big help. Most all of my vacs bearings need greasing and I don't know how to grease them if they are supposedly sealed bearings... I would just take them to a vac shop to service them but there are no vac shops around here.. I live in the Boonies....
For the price of the bearing, you might considering replacing the complete bearing vs. just greasing it. If you replace, use a good bearing such as SKF, FAG, NTN.
