YFW-300/YFW-500

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

The YFW-300 and YFW-500 are hard-bearing balancing machines designed for manufacturers of fans, motors, crushers, drums, textile machinery, and medium to small agricultural equipment. With their safe hard-bearing structure, easy calibration, and simple operation, they deliver reliable and efficient balancing performance.

A key advantage of these fan impeller balancing machines is their ability to handle workpieces with a rotational diameter of up to 1200 mm, making them suitable for the dynamic balancing of large fan impellers. They are also well-suited for other high-speed rotating parts such as flywheels, pulleys, cutter discs, and crankshafts.
