Roller Air Bearing X For Rotating Outer Rings
For maximum precision, smooth bearings and optimum synchronization

With a roller air bearing X, your bearings are contactless and therefore friction-free. This is achieved with a thin layer of compressed gas. The air serves as a lubricant that flows out of porous material. This allows you to move your load with high precision, dynamically and smoothly.

With a roller air bearing, the shaft is fixed and does not rotate. Air is also supplied via the shaft. The roller air bearing X enables you to achieve rotating outer rings with an accuracy of 0.025 µm.

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.
