Air Bearing Table Design

Planar xy table consists of moving element called forcer which glides on the frictionless air bearings over the special waffle like surface called platen.

Air bearing table design.

Oav roller air bearing. An air bearing is a non contacting system where a gas film usually air acts as the lubricant that separates the two surfaces in relative motion typically this being a rotating shaft and a stationary radial journal or axial thrust bearing. The two surfaces do not touch thus avoiding the traditional bearing related problems of friction wear particulates and lubricant handling and offer distinct advantages in precision positioning such as. As a result planar xy table offers greater reliability and performance realized through design simplification and elimination of wear prone components.

Air bearings also known as aerostatic or aerodynamic bearings are fluid bearings that use a thin film of pressurized gas to provide a low friction load bearing interface between surfaces. New way air bearings 50 mcdonald blvd. All hovair automotive air bearing tables have a patented starbase design utilizing six heavy duty air bearings that are used to float the table top. We offer a line of flat rectangular air bearings designed to meet the non contact requirements at low cost while yielding high performance.
