If you are careful, at the ends of the hamster cage is some tape that is covering the bearings. If you can remove the tape, and use a degreaser to remove the old lube, you can relube the bearing with a silicone type lube and then wipe it clean before applying the tape back on, might to add tape to the old tape. At the same time, you can use a paint brush to sweep out the caked on dirt that has built up around the fan.
Dust and Dirt is the scourge of computers everywhere!
