    Features
    • Uses a gearbox with AC motor combination to drive the rotor through a universal joint.
    • Before starting, operators only need to set the distance between correction planes, the distance from correction planes to supports, and the radius. With these adjustments, unbalance value and phase are displayed accurately in a single run.
    • Suitable for special rotors such as those with inner or outer overhanging masses.
    • Available with different sizes of universal joints to match specific balancing requirements.

    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.

    For accurate readings, balancing machines should be installed on a solid industrial floor to avoid external vibrations. This stable setup is especially important for hard-bearing models, where force measurement is used to calculate unbalance.

    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.
