To meet the high accuracy requirements of positioning tasks, the use of nozzle air bearings and surface air bearings for linear and rotary applications has become indispensable in industry. We combine your technology with our know-how. Systemtechnik Hölzer GmbH supplies customized air bearing solutions made of metal, plastics and composite materials for all applications. The spectrum includes all common air bearing technologies - nozzle air bearings with varying numbers of nozzles for linear and rotary applications in the form of support, guide or compensating bearings, as well as transport bearings made of sintered material for non-contact handling of sensitive materials, such as displays and photovoltaics. Hovering on 4 μm air tons In connection with ever higher accuracy requirements for positioning tasks, the use of granite- or steel-based air bearing guides has steadily spread in recent years. We combine your technology with our know-how. Precision air bearings - technology of the future With a much higher precision than e.g. rolling bearing based linear guides, the interaction of air bearing and linear motor technology offers the perfect solution. 1. efficiency The efficiency/utilization factor of the Hölzer bearing system technology is high due to its design, as the maximum bearing pressure can build up over a very large area of the bearing face before it is released to atmospheric pressure. 2. stiffness More important than the efficiency in terms of load carrying capacity of an air bearing is its stiffness, which is defined by the ratio of load change to flight height change. The basic stiffness of an air bearing also depends on its design.
