Air bearing bush
For frictionless bearings, maximum precision and optimum synchronization

Air bearing bush

With an air bearing bush, you have contactless and therefore frictionless bearings. This is achieved with a thin layer of compressed gas. The air serves as a lubricant that flows out of the porous material. This allows you to move your load with high precision, dynamically and smoothly.

The air bearing bush makes air bearing technology available for designs with round shaft guidance. The components run on standard precision steel shafts and are available in metric or English sizes. Titanium and other special materials can also be used as an option to maximize rigidity and load capacity.

FAQ

Can another gas also be used? Compressed air is commonly used in industrial applications. Compressed nitrogen is also possible, but this also changes the air bearing values. All specifications must be considered when using compressed air.
How clean must the supply air be? Cleanliness class between 3 and 4 of ISO 8573.1
How are air bearings maintained? The air bearings are maintenance-free.
Can I clean the surface? Use a soft cloth with isopropyl alcohol and let it dry.
How do I install an air bearing? Please read the instructions before starting. Each type of air bearing must be installed differently and this should be taken into account during the design phase.
How does an air bearing maintain stability and damping effect? Air bearings are coated with a special epoxy resin that seals the pores on the surface where no airflow is desired. The design thus forces the airflow in the direction of the friction-free surface. This results in greater rigidity, more stability and better damping properties.
