Balancing Machine for Drive Shafts Series RBRQ200x - eg-ar1 (CB)

  • Automatic measuring sequence
  • Simulation of operational conditions through high speed measurement in hard-bearing support pedestals
  • Unbalance correction by welding or drilling
  • New microprocessor-controlled measuring unit
  • Proven protective enclosure for drive shaft failure and noise protection


Machine design is ideally suited for balancing vehicle drive shafts. Arrangement of the machine components takes ergonomic requirements into consideration. Vertical arrangement of the correction units.
Extremely flat machine base, specially designed for high speed measurement. Isotropically supported bearing pedestals with heavy duty, precision spindles. Variable speed AC main spindle motors are standard equipment.



Range of application

Measurement and correction of unbalance in single and multi-piece drive shafts of passenger vehicles, light and heavy duty commercial vehicles.
Balancing and correction capacity for manufacturing, testing and inspection at vehicle manufacturers and component suppliers plants.
High speed measurement of unbalance close to or at operating speed.
Unbalance correction through spot or projection welding using medium frequency techniques, of preformed correction weights.
