Product List
A sleeve type bearing consists of the sleeve made out of oil absorbent material, oil and the shaft. With this simple construction it is very easy to mass produce quantities of sleeve bearing type fans at a low cost. The best operation is at lower temperatures. When used in high temperature environments the oil begins to evaporate, resulting in a loss of lubrication. This increases temperature and premature wear, causing shorter than expected life for this type of fan.
