Design And Development Of Orifice-Type Aerostatic Thrust Bearing, Jitendra P. Khatait

Jitendra P Khatait

Air bearings are extensively used in precision machines and equipment in recent years. Unlike conventional bearings, there is no physical contact between the sliding surfaces. The moving surface can glide smoothly on the other surface, minimising the control effort to achieve high accuracy and precision. Analytical study was carried out avoiding complexities in the formulation. The governing parameters were kept at a minimum. This helped in easy understanding of the dynamics and performance behavior of the air bearings. A simple design methodology was also developed to assist in the design or the selection process of the bearing. Finally, a three-dimensional …
