Due to their modular structure, these machines can be adapted easily to the task in hand. The length of the machine bed is dependent on the length of the rotor, the required height of the bearing pedestals is determined by the rotor diameter. If the rotor is mounted on its own bearing journals, these will be supported by roller carriages. Depending on the requirements imposed by the rotor, sleeve bearings may also be used.
Rotors requiring high torques are driven through variable-speed gearboxes and universal joint shaft. Lightweight rotors with smooth surfaces may be driven with the help of a belt drive system.
With the appropriate machine design and a suitable protection device the machines can also be used for high-speed balancing
Bearing force monitoring for automatic shut-down in case of overload
Contact-free measurement of concentric running of rollers
Graphical display of acceleration curve with 1f and 2f measurement
Wide range of supplementary modules, e.g. for mass correction
