BiaoFeng bearing fan bearing common sense

Bearing type is refers to the air cooled radiator fan the use of bearing type. In mechanical engineering, bearing type very much, but in the radiator products use also so a few kinds: use the sliding friction sleeve bearing and use of rolling friction of ball bearing and two kinds of bearing form mixed these three. In recent years the radiator manufacturer in bearing aspects introduced new technology, such as maglev bearing, water wave bearing, core bearing, rifle bearing are also above to the basic form bearing improved and become, operation principle or did not change. Ordinary air cooled radiator mainly use oil bearing and ball bearing.

Oil bearing is the use of sliding friction sleeve bearing, the use of lubricating oil as a lubricant and drag reduction agent, the initial use on low noise, manufacturing cost is low also, but this kind of bearing wear serious, life a ball bearing has the very big disparity. And the bearing use time a long, because the cause of oil seal (computer radiator products may not use high-grade oil seal, in general, is ordinary paper oil seal), lubricating oil will gradually volatile, and dust will also enter the bearing, thus cause fan speed slow, noise problem such as increasing, serious still can because bearing wear cause fan eccentric trigger violent vibration. Appear these phenomena, or open the oil seal oil, or only out for another new fan.
