VART Air Bearing Rotary Stage VART200
VAR series air-bearing rotary stages offer ultrahigh rotational accuracy, stable constant-speed operation, extremely low axial and radial runout, and high rigidity. They result from continuous optimization using the development team's expertise in materials, structures and simulation analysis. Noncontact air bearings enable frictionless rotation, allowing VAR stages to achieve submicron angular accuracy.
