Air Bearing Guide With Square Profile
For maximum precision, smooth operation and optimum synchronization

Luftgelagerte Führung mit Vierkant-Profil

The air bearing guide with square profile consists of current air bearings. It is made from lightweight aircraft-grade 7075-T6 aluminum, which is vibration-free and enables maintenance-free movements. The guide is supplied ready for installation and has an integrated parking brake function, which results from the preload of the air bearing and enables maximum accuracy and positioning.

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.
