Thrust Air Bearings and Bushings

The OAV Thrust Air Bearing is a breakthrough innovation in air bearing technology. For the first time, an air bearing is available that fully integrates and works on a three-way frictionless surface. The OAV Thrust Air Bearing configurations run on standard sized shafting for fixed, linear motion while maximizing rotational motion with ultra precision and zero friction using aerospace quality aluminum.

​OAV Air Bearings have higher stiffness and excellent geometric performance. The OAV Thrust Air Bearing preloads both the horizontal and vertical surfaces with opposing thin films of pressure. This maintains the perfect gap for ultimate tolerance, and the surface design of the bearing equally distributes the air and pre-loads it over the entire surface area. The result is outstanding stiffness with maximized performance.
