Motor bearings, also known as motor bearings or motor bearings, are special bearings specially used on 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 bear the idling components on the shaft. The concept of bearing is very broad. There are four types of bearings commonly used in motors, namely rolling bearings, sliding bearings, spherical plain bearings and oil-impregnated bearings. The most common motor bearings are rolling bearings, which are bearings with rolling elements. Sliding bearings generally refer to bearings without rolling elements, that is, bearings that perform sliding motion.

Powder metallurgy bearings are made of metal powder and other anti-friction material powders that are pressed, sintered, shaped and immersed in oil. They have a porous structure. After being soaked in hot oil, the pores are filled with lubricating oil. Du
