The AluLine AL-80 is a high-precision linear aerostatic bearing, consisting of an aluminum spindle sleeve and a cage. The essential advantage of the bearing consists in that it is not subjected to punctiform loads, in contrast to the concept of mechanical bearings, since the load is distributed over a relatively large area.
Another advantage is its high shock and vibration resistance, since it involves no mechanical contact whatsoever.
The primary application lies in the scope of individual axes for positioning systems or multi-axis systems, such as for example in measuring machines.
These types of aerostatic bearings are also suitable for clean room applications, since the exhaust air is filtered.
Outfitted with a precision spindle drive in combination with a high-definition incremental measuring system, an exceptionally good process and positioning accuracy with moderate rigidity and moderate linear velocity can be realized.
