Air bearings are quite new to most people. Although they are not as popular as some other kinds of bearings, they are still very important in many aspects. Due to their importance, I think it is rather necessary for us to learn something about them. You can get more info about Air Bearing via http://www.hovair.com/airbearing/how-do-air-bearings-work/.

Aerodynamic bearings and aerostatic bearings are two basic types of precision air bearings. Compared to types such as ball bearings and needle bearings, these two kinds seem like rather complicated. Let us look at the first type.
They depend on relative motion between the surfaces and usually some type of spiral grooves to draw the air between the bearing lands. This kind of bearings is often referred to as foil bearings or self-acting bearings. There are many examples of them like thrust bearings for electrical generator turbines.
At that point, it's a great opportunity to learn about the second classification. This kind of items requires an outside pressurized air source which is presented between surfaces by exactness openings, scores, steps or permeable remuneration methods. It is expected the air source that these items can keep up an air hole without relative movement between the surfaces.
Air heading has an extensive variety of utilization. They can be connected in testing types of gear, fast types of gear, and exact machine devices, and so on. They have many unique points of interest. For instance, they have fast and high exactness capacities close to zero grinding and wear, and no oil necessities.
