Ball bearing performance
- Jul 19, 2018 -

The rolling friction of rolling bearing is smaller than that of journal bearing, so the temperature of friction will be relatively low at the same speed.

Ball bearings are generally used in low load mechanical transmission equipment. Because the bearing area of ball bearing is small, it is easy to have serious mechanical damage in high speed operation, so the needle roller bearing is often adopted to increase the bearing surface, improve the mechanical transmission efficiency and reduce the mechanical damage in the heavy load mechanical transmission.

Ball bearings change the friction mode of bearing, using rolling friction, this way is more effective to reduce the friction between the bearing surface, improve the service life of the fan bearing, and therefore extend the service life of the radiator. The drawback is that the process is more complex, cost increase, and also brings higher work noise.
