Review on Air Bearings and Its Applications
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 3
Abstract
Bearings are machine elements that allow components to move with respect to each other. A little consideration will show that some part of power wasted in overcoming the frictional resistance and due to the contact of surfaces large amount of wear and tear takes place between the contacted surfaces.Hence to avoid wear and tear in sliding contact bearing and to reduce frictional resistance the thin layer of fluid is introduced which is called as lubricant.Air bearing are introduced to reduce such frictional resistance and wear of sliding contact bearings.Air bearings are bearings that uses a thin film of pressurized air to provide low friction load-bearing interface between surfaces. There is small gap between two surfaces i.e. two surfaces do not touch. As these bearings are contact free various problems in traditional bearing like friction, wear, particulates, and lubricant handling are avoided. Also there are advantages like precision positioning, such as lacking backlash and static friction, as well as in high-speed applications.
