In the  industry, cartridge bearings refer to a bearing assembly that can be entirely removed and replaced into the component such as a hub or bottom bracket. Traditionally, each bearing
assembly in a hub would consist of four separate components; a cup, a cone, a retainer and balls. Each of these components (with the balls being held by the retainer) would be assembled as individual parts and then adjusted with nuts and threaded axles on a hub or spindle assembly. Cartridge bearings replace this four component assembly with one complete unit that is sealed with rubber seals. A radial cartridge bearing consists of an inner and outer race, a retainer holding the balls and then two seals to keep the grease in and the elements out. There is no adjustment feature for these bearings as they are made with internal clearance or play. They are typically mounted by pressing them into a bore, such as both sides of a hub flange, and then a slip fit axle is run through with stops behind the inner race of each bearing. Nuts or top caps lock the bearings and axle into place. Again, there is some internal play when they are tightened down. When the bearings wear out or they get rough or contaminated, they can be removed entirely for servicing or replacement.
