Most Common Methods

• Preload by piston bearing (any number of piston bearings)
• Preloading by magnets (directly integrated into air bearings or stand-alone magnet plate)
• Preload by vacuum (integrated directly into air bearings)
• preload due to weight

Advantages of statically determined storage:

• Self-adjusting storage
• Smaller manufacturing tolerances necessary (parallelism of the guide surfaces not required)
• High reliability in operation (temperature fluctuations, etc. have no effect on storage)

Advantages of statically overdetermined storage:

• Double the rigidity of the bearing with the same bearing size
• Temperature expansion centered on storage Figure Explanation

Why is there a maximum load and a recommended load?

• Preload necessary to achieve air bearing performance. > recommended load
• Additional external forces may occur up to the maximum load

Can a roller bearing simply be replaced by an air bearing?

Usually not without making adjustments to your design.
