The code number of the motor bearing and its common model
Some of the mechanical equipment that rotates in the factory is driven by electric motors. The quality of the electric motor is related to the running smoothness of the bearings used to some extent. It requires low noise, economical and simple support structure, and usually uses deep groove ball bearings.
Motor bearings, also called motor bearings or motor bearings, are a special bearing product that is specifically applied to electric motors or motors. The bearing used in the motor is a part that supports the shaft. It can guide the rotation of the shaft and can also withstand the components that are idle on the shaft. The concept is very broad. There are four types of bearings commonly used in motors, namely rolling bearings, plain bearings, joint bearings and oil-impregnated bearings. The most common motor bearings are rolling bearings, ie bearings with rolling elements. A plain bearing refers to a bearing that has no rolling elements, that is, a bearing that performs a sliding motion.
Motor bearing code consists of:
1. Pre-code - indicates the sub-parts of the bearing.
2. Basic code - indicates the main features such as the type and size of the bearing.
3. Post-code - indicates the accuracy of the bearing and the characteristics of the material.
Motor bearing works
Motor rolling bearings use smooth metal rolling elements and lubricated inner and outer ring metal faces to reduce friction. These balls or rollers "bear" the load and support the motor shaft so that the motor (rotor) can rotate smoothly.

There are many bearings for electric motors. The combination of deep groove ball bearings and cylindrical roller bearings, angular contact ball bearings and cylindrical roller bearings are common combinations.
