Ball Bearing Performance
- Jan 17, 2018 -

And the hardness of the retainer is lower than the ball and ring, its materials are metal (such as: carbon steel, aluminum alloy) or non-metallic (such as: Teflon, PTEF, polymer materials). Rolling bearing (fellow bearing) is smaller than the rotational frictional resistance of the journal bearing (journal bearing), so the temperature produced by the friction is lower under the same rotational speed.

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

Ball bearings change the friction of the bearing, using rolling friction, this way more effectively reduce the friction between the bearing surface, improve the service life of the fan bearing, and therefore the radiator's service life is prolonged. The disadvantage is that the process is more complex, the cost is increased, but also bring higher working noise.
