Air Bearing Benefits: Large Load Capacity

Air bearings can support heavy loads, allowing them to be applied to many industrial machine tool applications.

Air bearing design can incorporate heavy load-carrying capacity, high stiffness capability, or a combination of the two. In many air bearing applications where spindle speeds are relatively low, large diameter radial and axial bearings can be incorporated.

Radial bearing loads up to 500kg.
Axial bearing loads up to 1000 kg.

The graph to the right shows the load capacity with increasing spindle shaft diameter.
