What are the main materials of car plane bearings?

There are many main materials of automotive flat bearings. According to different uses and requirements, selecting the right material can improve the service life and performance of bearings. The following will introduce the main materials and characteristics of automotive flat bearings:

1. Cast iron material: Cast iron is one of the most commonly used bearing materials, with good toughness and wear resistance, suitable for bearing medium load and medium speed occasions. Flat bearings made of cast iron are generally used for transmission components and low operating speeds.

2. Aluminum alloy material: Aluminum alloy has the advantages of light weight, high strength, good thermal conductivity and corrosion resistance, suitable for high-speed rotation, high temperature and high load occasions. Aluminum alloy flat bearings are mostly used in high temperature and high speed parts such as automotive engines and clutches.

3. Bronze material: Bronze is a commonly used bearing material, with good wear resistance and thermal conductivity, suitable for medium load and low speed rotation occasions. Bronze plane bearings are generally used in automotive suspension systems, steering systems and other components.

4. Polytetrafluoroethylene (PTFE) material: PTFE is a self-lubricating and good corrosion resistance material, suitable for high-speed and low load occasions, with good anti-friction performance. PTFE flat bearings are mostly used in automotive lubrication systems, steering systems and other components.

5. Polyester material: Polyester material has good wear resistance and corrosion resistance, suitable for medium load and medium speed rotation occasions. Polyester flat bearings are mostly used in automotive transmission systems, braking systems and other components.

6. Stainless steel material: Stainless steel has good corrosion resistance and high hardness characteristics, suitable for high temperature, high speed, high load occasions. Stainless steel flat bearings are generally used for key components such as automotive engines and clutches.

In general, the main materials of automotive flat bearings are cast iron, aluminum alloy, bronze, PTFE, polyester and stainless steel, etc., according to different requirements to choose the right material can improve the performance and life of the bearing. When selecting the material, it is necessary to consider the bearing's use environment, load, speed, temperature and other factors to ensure the normal operation and safety performance of the bearing.
