YFW-100/YFW-160

Hard-bearing balancing machine for dynamic balancing of fan impellers and blowers

The YFW-100 and YFW-160 are hard-bearing balancing machines widely used for the dynamic balancing of fan impellers and blowers. Their hard-bearing design ensures that the operating speed remains well below the system’s resonance speed, guaranteeing safe and stable operation. The fan impeller balancing machines are also suitable for balancing electric motor rotors, small fan rotors, crankshafts, pulleys, and flywheels.
