Air bearings are a type of mechanical bearing that uses pressurized gas (usually air) to create a thin film of gas between two surfaces. Air Bearings are known for their low friction, high accuracy, and clean operation, which makes them suitable for a wide range of applications.
Compared to other types of bearings, such as rolling element bearings and hydrostatic bearings, air bearings have many advantages:
Low friction: Air bearings have extremely low friction due to the thin film of gas that separates the moving and stationary surfaces. This makes them ideal for applications that require precise movement or low-friction operation. High accuracy: Air bearings are known for their high accuracy and stability. They can maintain a precise position and orientation over long periods of time, making them ideal for applications that require precise measurement or control. Clean operation: Air bearings do not require any lubrication or maintenance, making them ideal for applications where contamination or debris could be a concern. They can also operate in a wide range of temperatures and environments without degrading. Long lifespan: Air bearings have a long lifespan compared to other types of bearings, as they do not wear out or require maintenance. This makes them cost-effective over the long term.
