Bearings are an essential component in contemporary machinery and equipment. The bearing industry is developing rapidly. There are few to many bearing types, product quality and technical level from low to high, and the industry scale from small to large. A complete range of products has been formed—production A more intelligent professional production system. Ball bearings are generally used in low-load mechanical transmission equipment. Because the bearing area of the ball bearing is small, severe mechanical damage is easy to occur under high-speed operation. Therefore, in the heavy-duty automatic transmission, needle roller bearings are often used to increase the bearing surface, improve the mechanical transmission efficiency, and reduce Mechanical damage.
The ball bearing is a type 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 the power transmission process and improve the transmission efficiency of mechanical power by rolling. Ball bearings cannot withstand heavy loads and are more common in light industrial machinery.
Ball bearings mainly include four essential components: ball, inner ring, outer ring and cage or retainer. General industrial ball bearings meet the AISI52100 standard. Balls and bracelets are usually made of high chromium steel. Rockwell C-scale hardness is between 61-65.
Ball bearings change the way bearings are rubbed. The use of rolling friction reduces the friction between the bearing surfaces more effectively, increases the service life of the fan bearings, and therefore extends the service life of the radiator.
Ball bearings are operated using round metal balls, which are point contacts, so activation is easy. Coupled with the use of ball bearings in conjunction with springs, the weight of the entire fan rotor is located on the ball imported bearings and is indirectly supported by the springs so that it can be used for portable products with different directions and angles, but it must still be prevented. To prevent damage to the ball bearings, which can cause noise and reduce service life.

The ball bearing changes the friction model of the bearing and adopts rolling friction. This method more effectively reduces the conflict between the bearing surfaces, improves the service life of the fan bearing, and therefore extends 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.
First, the advantages of ball bearings
1. Metal bead operation is point contact, so it is easy to activate service.
2. It can be used for portable products that are often operated at different placement angles and directions (but to prevent falling or falling). 3. Long service life (compared with oil-bearing).
Second, the disadvantages of ball bearings
1. The bearing structure is quite fragile and cannot bear the impact of external force.
2. When the motor rotates, the rolling of the metal beads will produce a more considerable noise.
3. The price is high, and it cannot compete with the oil-bearing at the cost price.
4. The source and quantity requirements of ball bearings are not easy to control.
5. The ball bearing uses the elasticity of the spring to position it, which is challenging to assemble.
Third, the characteristics of ball bearings
1. Guarantee of high accuracy
The ball screw is produced continuously with the world's highest level of machinery and equipment, and in particular, the temperature and humidity are strictly controlled in terms of the factory environment in each process of grinding, assembly, and inspection. The perfect quality management system guarantees full accuracy.
2.No backlash, high rigidity
The ball screw can be preloaded. Because of the preload, the axial clearance can reach a negative value, thereby obtaining higher stiffness. (Ball bearings can add pressure to the ball. (Enhance the stiffness of the silk mother part)
