Aerostatic bearings

Aerostatic bearing systems are one of the latest technical devolopments of ZOLLERN to complete the range of bearing solutions. Aerostatic bearing solutions are characterized by the following features:

  • Lifetime theoretical unlimited
  • No vibrations by rolling elements
  • No friction – thereby max. positioning accuracy – no stick slip effect
  • Very precise radial and axial run-out
  • No oil supply/return system and oil cooling unit necessary
  • Air supply by existing compressed air system


Application example

Aerostatic round table with direct drive

Combined radial / axial bearing
Running surfaces coated with slide coating providing emergency running properties
Angle measuring device integrated
Torque motor integrated, free air convection
