In recent years air bearings have been used in several fields: for measuring machines, machine tools, control benches, optoelectronic applications, etc. Due to their particular properties they have reached a large diffusion: precision, extremely low friction, good rigidity, endless life, vibration-proof, the possibility of moving considerable weights using minimum power.
Moreover we can obtain excellent results by applying air bearings to the granite guides and then reaching linearity precision of about 0.2 μm/mt. In order to facilitate the conception of machines, air bearings are manufactured in standard sizes and circular shapes to obtain their peak efficiency (we can supply right-angled shaped too, but their efficiency shrinks in relation to the area).
This article is made from an aluminium alloy that has been anodised for strength. The sliding area is lapped. We produce two versions of air bearings:
AB 0480/0486: ADJUSTMENT AIR BEARINGS
fitted and adjusted with thin screws which operate on a steel ball located in the proper seat.
AB 0487/0493: CONTRAST AIR BEARINGS
they have to be fitted inside proper seats generally obtained from the cart itself in a way to exercise a regular thrust on the bearing through compressed - feedings of air. They usually have to be placed together with the adjustable bearings.
