Generally, the reliability of the bearing of the cooling fan directly affects the length of the service life of the cooling fan. The common cooling fan bearings are ball bearings and oil-impregnated bearings, which are currently widely used in the market. Although cooling fans are often used, there are still many people who still don’t understand the difference between the ball bearings of cooling fans and oil-retaining bearings?
Ball bearings are rolled by metal balls, which belong to rolling friction. The contact surface is small and the friction coefficient is also small. Oil-impregnated bearings have sliding friction, and the contact surface is large. After a long time, the oil will quickly evaporate, which is easy to cause excessive wear of the bearing, increasing the friction coefficient, the noise will become greater and the life will be shorter.
Usually, ball bearing fans need two bearings. Single ball bearing still has oil bearing composition, while double ball bearing is more advanced than single ball bearing. Generally, the life of oil-impregnated bearings is generally 25,000 hours under the same environmental conditions, 30,000 hours for single ball bearings, and more than 50,000 hours for double ball bearings.
The oil-containing bearing of the cooling fan is sintered with copper-based powder. Lubricating oil needs to be added to reduce the sliding friction. If the fan works for a long time without adding lubricating oil, the oil in the bearing will evaporate and become dry, increasing friction. The fan does not run smoothly, and the speed will slow down or not rotate. In ball bearings, sliding friction is replaced by rolling friction. The small friction coefficient improves the shortcomings that the friction coefficient is easy to change. Therefore, the running stability is strong and the service life is relatively longer.
