In the machinery industry, IKO, many different kinds of bearings,Material Of Bearings http://www.abtbearings.com/ but used in radiator above a few have been IKO bearing types are:
1, the sleeve bearing (sliding friction);
2, ball bearing (rolling friction);
3, magnetic bearing;
4, water bearing;
5, core bearing;
Six, bearing, etc.,
Magnetic bearings, water wave magnetic core of bearings, bearings, bearings and so on also are all of the above two kinds of sleeve bearing and rolling bearing is improved, and principle of work and there is no change.
In the ordinary air cooled radiator now main use IKO bearing oil bearing and ball bearing.
Oil bearing
Oily IKO bearing sleeve bearing is the use of sliding friction, use oil as a lubricant and drag reduction agent, began to work when using low noise, also lower the manufacturing cost, but IKO bearing wear serious, life is much lower than ball bearings. And this IKO bearing using a long time, because of the reason of the oil seal (computer radiator products can't use high-grade oil seal, oil seal is the ordinary paper) lubricating oil will gradually evaporate, the dust will enter the IKO bearings, thus causes the fan speed is reduced, increasing problems such as noise, serious still can because IKO bearing wear caused fan eccentric caused violent vibration.
Ball bearing
Ball bearing has changed the way of IKO bearing friction, adopts rolling friction, this way is more effective in reducing the IKO bearing frictional resistance, effectively improve the service life of the fan bearing, thus to extend the service life of the radiator. Is more complicated manufacturing process, leading to higher costs.
