With a radiax air bearing, 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. Radiax air bearings enable axial and radial air bearings, which is a groundbreaking innovation in air bearing technology.
The rotary movement is supported with the highest precision and without friction, which corresponds to a radial bearing. The axial bearing preloads both the horizontal and vertical surfaces with opposing thin-film pressure. This maintains the optimum gap tolerance.
The surface design of these air bearings distributes the air and preload evenly over the entire surface. The result is excellent rigidity and maximum performance in the form of a radiax air bearing.

Infinite service life, as maintenance-free. Fast and smooth movements that do not jerk even at the highest resolution. Much more precise positioning is possible with air bearings. There is no loss of energy and no source of heat due to friction. Free of lubricants or other lubricants.
