This is a new class mechanisms characterized by extremely high resolution and small time constant, in which errors such as backlash, radial and axial play, dead zone and low velocity stick-slip motion at are alleviated.

Active bearings integrate both drive unit and bearing into one machine component. An additional feature is the possibility of adjusting in space quasi-static displacements of piezoelectric transducer.

The prototypes of this prototype are many and varied - they include precision measuring systems for dimension error control, multi-functional measuring devices and various types of supports of precision engineering, including devices used in super finishing operations.
