Air cushion bearing unit AB series

Air Bearing are bearings that use a thin film of pressurized air to provide an exceedingly low friction load-bearing interface between surfaces. The two surfaces do not touch. It prevents the traditional bearing-related problems of friction and lubricant handling. And offers distinct advantages in precision positioning, such as lacking backlash and static friction. Fluid film of the bearing is air that flows through the bearing itself to the bearing surface. The pressure between the faces of the bearing is enough to support the working loads. Thus, there is a differentiation that has to be made between hydrodynamical bearings, which establish the air cushion through their movement. Air bearings are being mainly used in precision machinery tools and fast running machines.
