Range of Application

Universal balancing machines series HM2-HM30 are designed for accurate balancing of a wide spectrum of rotors. They are suitable for balancing cylindrical rotors with integral shaft journals and for balancing disc shaped rotors on balancing arbors. Typical rotors are electrical armatures, rollors, spindles, turbo charger rotors, crankshafts, ventilators, pump impellers, drive assembly components, and gear wheels. 

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.
