Air bearings are devices that utilize principles of aerodynamics to support and rotate bearings. It is a high-precision bearing that is non-contact, wear-resistant, pollution-free, noiseless, and vibration free, with advantages such as high speed, high precision, high stiffness, and high reliability. Air bearings are widely used in high-speed machinery, precision machining, semiconductor manufacturing, optical instruments, medical equipment and other fields.

 

The main products of air bearings include:

 

1. Gas static pressure bearing: Using gas static pressure to support bearings, it has the characteristics of high precision, high stiffness, and high speed, and is widely used in high-speed machinery, precision machining, and other fields.

 

2. Pneumatic bearings: Using the principles of aerodynamics to support bearings, they have the characteristics of high speed, high precision, and high stiffness, and are widely used in semiconductor manufacturing, optical instruments, and other fields.

 

3. Magnetic levitation bearings: Using magnetic field force to support bearings, they have the characteristics of non-contact, wear free, and vibration free, and are widely used in high-speed trains, wind turbines, and other fields.

 

4. Liquid bearings: Using liquid static or dynamic pressure to support bearings, they have the characteristics of high precision, high stiffness, and high load-bearing capacity, and are widely used in aerospace, shipbuilding, and other fields.

Air bearing (also known as air bearing) refers to a sliding bearing that uses gas (usually air, but may also be other gases) as a lubricant. Air has lower viscosity than oil, high temperature resistance, and no pollution, so it can be used in high-speed machines, instruments, and radioactive devices, but its load capacity is lower than oil. Air bearings are divided into three categories: air static pressure bearings, air dynamic pressure bearings, and squeeze film bearings. In general industry, air static pressure bearings are widely used.
