    Fan Impeller Balancing Machine

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

    The YFW-3000 is a hard-bearing balancing machine designed for medium and small fan manufacturers. With the capacity to balance impellers up to Ø3000 mm in diameter, it is ideal for testing and correcting unbalance in large fan rotors. Its integrated machine base allows balancing of multiple impeller sizes with ease, while offering the full functions of a general-purpose balancing machine. The system is easy to install and calibrate, delivers accurate and rapid measurements, and provides clear data display.

    Balancing machines are instruments that indicate if a rotating component, such as a rotor or fan, rotates in an unbalanced manner. If the component wobbles or vibrates a lot, the balancing machine will point out the imbalance so it can be corrected. The importance of balancing is directly related to the longevity of the rotating component and how well the component functions.

    Soft-bearing machines use flexible supports, making them sensitive to very small vibrations and suitable for lighter or smaller parts that require high accuracy. Hard-bearing balancing machines, on the other hand, use more rigid supports, so they are more suitable for larger and heavier rotors. Hard bearing balancing equipment may be less sensitive to tiny vibrations, but they are easier to set up and give reliable results across a wider range of workpieces.

    Balancing machines are used to rotating parts such as motor rotors, impellers, fans, flywheels, clutches, gears, pulleys, and brake drums. By correcting unbalance, they help reduce vibration, extend service life, and keep production running more smoothly.

    Balancing machines can be configured with belt drive, universal joint drive, or self-drive. Belt drive is usually chosen for smaller rotors that require accuracy, while universal joint drive delivers higher torque and is safer for heavier parts. Self-drive designs are used when the workpiece can rotate under its own power.

    Accuracy may be affected by operator handling, incorrect markings, or mismatched correction points. Technical issues such as damaged sensors, loose connections, or electronic failures can also play a role. Regular calibration and proper setup help keep results consistent.
