Motor plain bearings Details

    The bearing pad is made of split structure which contacts the core of Bearing housing with self-aligning function. The bearing tile is made of low carbon steel as 20# steel. Its surface coated with tin base Babbitt alloy (Domestic alloy ZSnSb11Cu6, imported alloy TEGO STAR738 which contains no lead); Its oil inlet edge was optimized design in order to ensure the safety, stability, reliability and durability of bearings.

     Bearing tile can be divided into 4 different types by the different axial thrust: type Q without thrust parts on two sides (no axial thrust load); type B plain thrust face with oil inlet slot on two sides (withstand small and temporal axial thrust load); type K with Fixed oil wedge thrust surface on two sides(withstand medium axial thrust load); type T with elastic circular thrust pads on two sides (withstand large axial thrust load). Elastic circular thrust pads has excellent damping characteristics and can absorb the axial impact load.The end cover bearings are able to replacement of Renk bearing,Zollern bearings,for example:EFZLB,EFZLQ,EZLB,ZMNLB,ZMNLQ,ZMZLB,ZMZLQ.

     To bearings used in working conditions characterized by large starting pressure (more than 1.5Mpa), frequent start or stop, long lasting stop, low starting power, low speed or frequent reverse rotation, it is recommended to adopt the bearing tile with high pressure oil lifting structure.

Is the relationship between motor plain sliding bearings and bearing seals closely related?

There is a close relationship between motor plain sliding bearings and bearing seals. The main function of the bearing seal is to prevent lubricant leakage in the motor plain sliding bearing and to prevent dust, moisture and other impurities from entering the bearing.
Bearing seals prevent lubricant leakage. In motor plain sliding bearings, lubricants play a key role in reducing friction and wear between bearings and shafts and reducing energy loss. If the lubricant in the sliding bearing leaks, the lubrication performance of the bearing will decrease, causing problems such as bearing overheating and increased wear, which will ultimately affect the normal operation of the motor. Bearing seals can effectively seal the lubricant leakage port, maintain the appropriate amount of lubricant in the bearing, and ensure the normal operation of the bearing.
Bearing seals prevent dust, moisture and other impurities from entering the bearing. At the motor working site, there is often a large amount of dust, moisture and other impurities. If these impurities enter the inside of the bearing, they will cause wear and corrosion of the internal parts of the bearing, reduce the service life of the bearing and even cause motor failure. Bearing seals can effectively block the intrusion of dust, moisture and other impurities, maintain a clean environment inside the bearing, and ensure the normal operation of the bearing.
The use of bearing seals can extend the service life of bearings. Bearings are very important components in motors, and their service life directly affects the reliability and stability of the motor. By using bearing seals, the adverse effects of the external environment on the bearing can be reduced, lubricant leakage and impurity entry can be prevented, bearing wear and corrosion can be reduced, the service life of the bearing can be extended, and the working efficiency and reliability of the motor can be improved.
The relationship between motor plain bearings and bearing seals is closely related. Bearing seals can prevent lubricant leakage and impurities from entering the bearing, maintain normal operation and proper lubrication of the bearing, extend the service life of the bearing, and improve the working efficiency and reliability of the motor.

Are motor plain sliding bearings suitable for long-term operation and high-load work?

Sliding bearings are an important mechanical transmission component, often used in motors and other equipment, and are suitable for long-term operation and high-load work. It reduces friction and wear by forming a lubricating film between the shaft and bearings, thereby ensuring the stable operation of the motor and its ability to withstand higher loads.
Under working conditions that require continuous operation of the motor, sliding bearings can ensure the stable operation of the motor. In the case of high-speed rotation or long working time, the sliding bearing uses a lubricating film to reduce the direct contact between the shaft and the bearing and reduce wear and friction. This lubrication method not only reduces energy loss, but also extends the service life of the motor.
Sliding bearings can withstand higher loads due to their structural characteristics. Sliding bearings usually consist of inner rings, outer rings, rolling elements and cages. A lubricating film is formed between the rolling elements and the cage, which can provide good support under high loads. This allows the motor to operate stably under high load conditions and ensures the motor's working efficiency and productivity.
Compared with rolling bearings, sliding bearings have the following advantages: First, they have a long service life. Due to the lubrication method and structural characteristics of the sliding bearing, it can maintain stable operation under long-term operation and extend the service life of the motor. Second, the friction loss is small. The lubricating film of the sliding bearing can reduce the friction between the shaft and the bearing and reduce energy loss. The third is high reliability. Since sliding bearings have no balls or rollers, they are not prone to failure. The fourth is adaptability. Sliding bearings are suitable for various working conditions and can cope with different loads and operating speeds.
In practical applications, appropriate sliding bearings need to be selected according to the working status and requirements of the motor. The materials, lubrication methods, lubricants, etc. of sliding bearings need to be selected and designed according to the actual situation. At the same time, during the use of sliding bearings, regular lubrication and maintenance are also required to ensure their normal operation and service life.
