Basic Design Guide
Air bearings are a fascinating phenomenon and tend to draw curiosity about what they can be used for. Due to their many benefits, air bearings are the best option to use for many applications. The number of applications is expected to grow exponentially over the next couple decades as the air bearing technology progresses and the world relies more and more on precision.
The following charts compare different air bearing products with one another.
Initial Design Considerations
Air Bearing Type: The first thing you will need to do is figure out which type of air bearing will work best for the application. Table 1 above, is a good source to start with.
Tolerances: Air bearing products provide and rely on precision. The smoother and more precise the surfaces are, the better the performance. If the guide surface cannot be as smooth as desired, consider using a larger bearing and high input pressure. It is important to design according to the tolerance requirements.
Guide Surfaces: Common guide surfaces include granite, hard-coated aluminum, ceramics, glass, stainless steel, and chromed steel.
Temperature: All standard air bearing products are designed to function at room temperature (70˚±30˚F). High temperature applications will require a custom air bearing, possibly with exotic materials, and may be a trial and error process.
Environment: It is important to make sure that oils and contaminants will not make contact with the air bearings. Air bearings work best in clean and dry environments.
Specifications and Size: Determine which size based on capabilities of the bearing and allowable size. It is always best to use one size larger than to use an air bearing that barely meets the performance requirements. A larger bearing will require less input pressure, have higher stiffness and better damping properties. The specifications of all standard air bearings can be found on www.oavco.com.
Preloading: Preloading the bearings will lower the air film thickness and increase the stiffness. The result is a better functioning air bearing. Although Air Bushings are automatically preloaded, it is important to incorporate preloading in any design using Flat Air Bearings. More information on preloading can be found in the Design With Flat Air Bearing section below.
Custom Air Bearings: Many applications are very specific or cannot fit a standard air bearing into the assembly. Therefore, OAV provides engineering services and custom air bearings to determine the best solution.
Once an air bearing type is determined, you may use the following information to design around the air bearings
