The tapered air bearing is the one of the most widely used form of roller air bearing in the industry. The OAV Tapered Roller Air Bearing consists of two main components - the inner assembly and the outer-cage. It is typically mounted in opposing pairs on a shaft, with air supply coming through the shaft with a cross-hole or inlet from the outer-cage.

The OAV Roller Air Bearing preloads both horizontal and vertical surfaces with opposing thin films of pressure. This maintains the perfect gap for ultimate tolerance. The surface design equally distributes the air and preloads it over an entire surface area, giving outstanding stiffness and maximized performance levels.
