Plain Bearings Industry knowledge

1.How does Plain Bearings achieve lubrication-free operation?
Plain Bearings, also known as plain bearings, are common mechanical elements used to support rotating or oscillating shafts. Unlike rolling bearings, plain bearings do not rely on balls or rollers to support the bearing load. Instead, they operate by lubricating medium to form a thin film between the friction surfaces. Plain Bearings usually consist of two parts: bearing shell and bearing bushing. The bearing shell is installed in the machine housing, while the bearing bushing is fixed to the rotating shaft. The friction between the inner surface of the bearing bushing and the shaft surface is reduced by lubricant, which allows the bearing to operate without lubrication. In non-lubricated operation, the choice of lubricant is crucial. Common lubricants include oils, greases and solid lubricants. The purpose of the lubricant is to form a film that reduces friction and wear and provides protection for the bearing bushings and shafts. The formation of the film reduces contact between direct metal surfaces, thereby reducing friction losses and wear and extending the service life of the bearing. In addition to suitable lubricants, the design and manufacturing process also play a vital role in the lubrication-free operation of Plain Bearings. For example, factors such as material selection, surface treatment and dimensional fit of bearing shells and bearing bushings must be precisely controlled to ensure that the bearings can operate effectively without the need for external lubrication. In practical applications, the lubrication-free operation of Plain Bearings makes them ideal in many applications, especially where high temperatures, high speeds or sealed environments are required, and where lubricant contamination needs to be avoided.

2. In which industrial fields does Plain Bearings play an important role?
Plain Bearings are widely used in various industrial fields, including but not limited to machine manufacturing, automotive industry, aerospace, energy industry and heavy machinery. They play an important role in these areas, providing support, reducing friction and wear, and ensuring the smooth operation of machines and equipment. In the field of machinery manufacturing, Plain Bearings are used to support rotating shafts, sliding guides and swing mechanisms. For example, in machine tools, conveying equipment and packaging machinery, Plain Bearings are widely used to support various rotating and sliding parts to ensure their smooth operation. In the automotive industry, Plain Bearings play an important role in key components such as engines, transmissions, suspension systems and steering systems. They are able to withstand loads at high speeds and high temperatures and provide reliable support and reduced friction, thereby extending the service life of automotive components. In the aerospace field, Plain Bearings are also widely used in components such as aircraft engines, landing gear, doors, and control systems. They can provide stable support and operation in extreme environments, ensuring safe flight of the aircraft. In the energy industry, Plain Bearings are used in equipment such as wind turbines, turbines and pumps to support the rotation of rotors and blades and reduce energy losses. In the field of heavy machinery, Plain Bearings are widely used in equipment such as excavators, loaders, cranes and agricultural machinery to support various moving parts and provide stable operation and long-term reliability. Plain Bearings play a vital role in a variety of industrial sectors, providing critical support and protection for the proper operation of machinery and equipment.

3. What are the unique advantages of Plain Bearings compared with other types of bearings?
Compared with other types of bearings such as rolling bearings, Plain Bearings have the following unique advantages:
Plain Bearings have a simple structure. Relative to rolling bearings, they generally consist of fewer parts and are therefore easier to design, manufacture and maintain. This makes Plain Bearings less expensive and more reliable in some applications. Plain Bearings are capable of withstanding higher loads and shock loads. Due to their larger friction surface, Plain Bearings are able to disperse and absorb larger loads, providing more stable support. Plain Bearings are suitable for high temperature and high speed operating conditions. In contrast, rolling bearings may have problems with balls or rollers falling off in high-speed and high-temperature environments, and Plain Bearings are more suitable for these harsh working conditions because they do not require rolling elements. Plain Bearings require no or very little lubricant to operate. In contrast, rolling bearings require lubricant to be added regularly, while Plain Bearings can operate without lubrication, reducing maintenance costs and the risk of lubricant contamination. Compared with other types of bearings, Plain Bearings have unique advantages such as simple structure, strong load-bearing capacity, high temperature resistance and high speed resistance, and no need for lubrication, making them the preferred bearing type in many applications.
