    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.

    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.
