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.

The frequency depends on usage intensity and operating environment. In most cases, calibration is recommended to calibrate balancing machines once a year, but for machines running under heavy workloads or harsher conditions, more frequent checks are advised to maintain precision.

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.

Vertical balancing models hold the workpiece upright, which is a better fit for disc-shaped components with a concentrated center of gravity, like brake discs or flywheels. Horizontal balancing machines hold the workpiece lengthwise and are commonly used for longer shafts, spindles, or motor rotors.

Standard vertical balancing machines can balance workpieces that range from around 80 mm up to 700 mm in diameter, with weights ranging from a few hundred grams to about 200 kg. For workpieces with sizes that aren't within this range, we can provide customized balancing solutions.

Depending on the workpiece and customer needs, unbalance can be corrected by drilling, milling, or adding weight with welded or attached counterweights. Both manual and automatic options are available.

They can be equipped with universal-joint drive, belt drive, or built-in motor spindle drive, depending on the application.

They support single-plane and dual-plane unbalance detection, as well as multi-plane measurement with sectional correction, which is especially useful for wind power rotors and blower impellers.
