Do you really know ball bearing terminology?

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

 Ball bearing terminology: The ball bearing mainly consists of four basic components: ball, inner ring, outer ring and cage or retainer, as shown. General industrial ball bearings meet the AISI 52100 standard. Balls and rings are usually made of high chrome steel with a Rockwell C-scale hardness of between 61 and 65.

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

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

 Ball bearing terminology: Ball bearing changes the friction mode of the bearing and adopts rolling friction. This method is more effective in reducing the friction between the bearing surfaces, improving the service life of the fan bearing and thus the service life of the radiator. extend. The disadvantage is that the process is more complicated, the cost is increased, and it also brings higher working noise.
