Importance of selecting materials and lubricants for seat-type sliding bearing bodies and bushings

As an important component of mechanical equipment, the performance and reliability of seat-type sliding bearings are directly related to the operating efficiency and life of the entire equipment. The material selection of the bearing body and bushing, as well as the selection of lubricants, are key factors in determining the performance of seat-type sliding bearings.

The body of seat-type sliding bearings is usually made of metal materials, among which high-strength alloy steel is a more common choice. This material not only has sufficient rigidity and strength to withstand large loads and impacts, but also has good mechanical properties and thermal stability, and can maintain stable performance in harsh working environments. The application of high-strength alloy steel enables seat-type sliding bearings to maintain high precision and long life when subjected to complex working conditions such as heavy loads, high-speed operation, and frequent start-stop.

However, a high-strength body alone is not enough to ensure the excellent performance of seat-type sliding bearings. The material selection of the bearing bushing is also crucial. As a component in direct contact with the shaft, the wear resistance, corrosion resistance and lubrication performance of the bushing directly affect the friction coefficient, wear rate and service life of the bearing. Therefore, the bushing of the pedestal plain bearing is often made of materials with good wear resistance, such as copper-based alloys, aluminum-based alloys or composite materials. These materials not only have excellent wear resistance, but also can form a good lubricating film with a variety of lubricants, thereby reducing the friction coefficient, reducing wear and increasing the service life of the bearing.

In addition to the material selection of the bearing body and the bushing, the selection of lubricant is also an important factor affecting the performance of the pedestal plain bearing. Lubricants play the role of reducing friction, reducing wear, cooling and rust prevention in bearings. It is crucial to select a suitable lubricant according to the working conditions and requirements of the pedestal plain bearing.

For high-speed bearings and high temperature working conditions, lubricating oil is a more ideal choice. Lubricating oil has good fluidity and can form a uniform lubricating film inside the bearing, thereby reducing the friction coefficient and wear rate. At the same time, lubricating oil can also take away the heat generated inside the bearing and play a cooling role. However, in bearings with better sealing and lower operating temperatures, grease is more suitable. Grease has high viscosity and adhesion, can form a stable lubricating film inside the bearing, prevent lubricant leakage, and play a role of rust prevention and lubrication.

The material selection of the pedestal plain bearing body and bushing and the selection of lubricant are the key factors that determine the bearing performance. By properly selecting materials and using lubricants, the bearing's load capacity, wear resistance and service life can be significantly improved, thereby ensuring the stable operation and efficient operation of mechanical equipment. Therefore, when designing and using pedestal plain bearings, the influence of these factors should be fully considered to ensure the best performance of the bearing.
