Ball bearings are a type of rolling bearing. Spherical alloy steel balls are installed between the inner steel ring and the outer steel ring to reduce friction during power transmission and improve mechanical power transmission efficiency in a rolling manner. Ball bearings cannot bear large heavy loads and are more common in light industrial machinery. Ball bearings are also called ball bearings.
Ball bearings mainly include four basic components: ball, inner ring, outer ring and cage or retainer. Ball bearings for general industrial use meet the AISI52100 standard. The balls and rings are usually made of high-chromium steel, with a Rockwell C-scale hardness of approximately 61-65.
Ball bearings are generally used in low-load mechanical transmission equipment. Because the load-bearing area of ball bearings is small, serious mechanical damage is easily caused under high-speed operation. Therefore, needle roller bearings are often used in heavy-load mechanical transmission to increase the load-bearing area, improve mechanical transmission efficiency, and reduce the Mechanical damage.
Ball bearings change the friction method of the bearing and use rolling friction. This method more effectively reduces the friction between the bearing surfaces, increases the service life of the fan bearing, and therefore extends the service life of the radiator. The disadvantage is that the process is more complex, the cost increases, and it also brings higher working noise.
