How much do you know about the ball bearing?

3,267 Published by admin1 May 11,2022

Ball bearing is a kind of rolling bearing. The spherical alloy steel ball is installed in the middle of the inner steel ring and the outer steel ring to reduce the friction during the power transmission process and improve the transmission efficiency of mechanical power by rolling. Ball bearings cannot withstand large heavy loads and are more common in light industrial machinery.

Ball bearing elements
Ball bearings mainly contain four basic elements: ball, inner ring, outer ring and cage or retainer. General industrial ball bearings meet the AISI52100 standard. The balls and rings are usually made of high-chromium steel, and the Rockwell C-scale hardness is about 61-65.

Ball bearing performance
The hardness of the cage is lower than that of the ball and the ring, and its material is metal (such as: medium carbon steel, aluminum alloy) or non-metal (such as: Teflon, PTFE, polymer material). Rolling bearings have smaller rotational frictional resistance than journal bearings, so at the same speed, the temperature due to friction will be lower.

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

The ball bearing changes the friction mode of the bearing and adopts rolling friction, which more effectively reduces the friction between the bearing surfaces, improves the service life of the fan bearing, and thus prolongs the service life of the radiator. The disadvantage is that the process is more complicated, the cost is increased, and it also brings higher working noise.
