Horizontal Type Microprocessor Based Dynamic Balancing Machines
( Model : FBM )

• Hard bearing type horizontal end driven two plane machines with microprocessor based / microcontroller based
  measuring panel.
• Suitable for balancing of different types of rotors like rotor of electrical machines, fly wheels, crankshafts,
  submersible pump rotors, etc.
• Measures & stores the unbalance in gms along with the angle for two selected correction planes on digital display.
• Additional bed length can be provided at extra cost for extra long rotors.
• Additional bed with gap bed arrangement is also possible to accommodate bigger diameter rotors.
• Minimum achievable unbalance upto 0.5 micron shift in c.g.
• Various Models – Suitable for rotors from 0.5 kg to 10,000 kg.
• Horizontal belt driven hard bearing two plane machines are supplied for rotors weighing from 0.3 kg upto 300 kg. • Unbalance indication either by stroboscopic method or photo scanning method sensitivity upto 0.5 micron.
• Computerized / Electronic versions with printer facility & special machines to suit customers requirements can also
  be supplied.
