Motor bearing, also known as motor bearing or motor bearing, is a kind of special bearing specially applied to motor or motor. 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 idling parts on the shaft. The concept of the bearing is very broad. There are four types of bearings commonly used in motors, namely rolling bearings, sliding bearings, joint bearings and oil-impregnated bearings. The most common motor bearings are rolling bearings, that is, bearings with rolling elements. Sliding bearings generally refer to bearings without rolling elements, that is, bearings for sliding motion, and some of them are Boundary Lubricants.
Code composition
Preface code-indicates the sub-component of the bearing.
Basic code—represents the main features such as the type and size of the bearing.
Post code-indicates the accuracy of the bearing and the characteristics of the material.
working principle
Motor bearings use smooth metal balls or rollers and lubricated inner and outer ring metal surfaces to reduce friction. These balls or rollers "carry" the load and support the motor shaft so that the motor (rotor) can rotate smoothly.
Bearing type
Most small and medium-sized motors use rolling bearings. Large and medium-sized motors also use rolling bearings. Bearings at both ends of small motors
Ball bearings (deep groove ball bearings) are used. Medium-sized motors use roller bearings on the load side (usually used for high-load conditions), and ball bearings on the non-load side (but there are also the opposite situations, such as 1050kW motors). The rolling bearings are lubricated with grease, but they are also lubricated with lubricating oil.
