Typical Configurations

Preload: Modular air bearings can be preloaded in many different ways.

1) Opposite bearing: The most common way is to preload with a bearing on the opposite end. This requires more space and adds more weight, but it provides for more stiffness and load capacity. To achieve the highest stiffness and balance, it is recommended to make sure the two bearings are placed opposite of one another, and that both surfaces are parallel to each other.
