Some bronze bearings are like metallic sponges filled with oil. During manufacturing, porous bronze is vacuum-soaked in lubricant, which slowly seeps out during use over many years. These self-lubricating bearings are common in home fans, small motors, and appliances that would be difficult to maintain. A single oil fill can last the lifetime of the device.
