The tapered air bearing is one of the most widely used forms of roller air bearings. 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 an opposing thin film of pressure. This maintains the perfect gap for ultimate tolerance. The surface design equally distributes air and preloads it over the entire surface area for outstanding stiffness and maximized performance.

For the first time, an air bearing is available that fully integrates and works on a three-way frictionless surface. OAV Thrust Air Bearings run on standard size shafting fix and maximizes stiff motion with precision.
We offer a line of flat rectangular air bearings designed to meet the non-contact requirements at low cost while yielding high performance. Often used as a standard, off-the-shelf solution for providing axial constraint in rotary motion applications. Available in metric and custom sizing made to order upon request.
OAV Non-Contact Static Web Rollers are used for applications that include the use of flexible materials while reducing contaminants and damage. Web tension, edge guiding, and more. Non-contact rollers replace the standard contact conveyor systems.
OAV Flat Round Air Bearings work on flat, nonporous surfaces such as granite, aluminum, glass, and ceramics. We offer a variety of sizes which can easily be used to customize your air bearing systems.
The OAV Modular Air Bearing design divides motion systems into smaller, installable parts. OAV Modular Air Bearings can be independently installed and used in different systems and different shapes.
The Open Pillow Block Air Bearing fulfills motion control needs requiring precision over longer distances compared to other rail guide solutions. The shaft with rail support offers increased rigidity compared to a bare shaft, minimizing deflections and maintaining straightness.
A high-precision, frictionless rotary platform integrating OAV roller air bearings with the integrated BLDC servo motor. Designed for applications demanding ultra-smooth rotation, high stability, and sub-micron positioning accuracy.
OAV Aerodynamic Foil Air Bearings are suitable for many high-speed applications. The OAV Foil Air Bearings novel design focuses on eliminating the adverse effects of rotational speed, unbalanced eccentricity, and rotor mass on the non-linear response.
Epoxy Bonded Air Bearings use a thin layer of epoxy to hold the air bearing to the desired surface. Epoxy air bearings offer higher stiffness, precision, and ability to withstand harsh environmental conditions.
