Features
  • The belt drive can be selected for smaller workpieces to achieve higher accuracy, while universal joint drive is used for larger rotors, providing higher torque and safer operation.
  • Dual-drive design works with a single measuring system, making it a cost-effective and easy-to-operate solution.
  • Combines the functions of both universal joint and belt drive balancing machines in one unit.
  • Can be equipped with the ZL-220 digital measuring system, which delivers quick and precise results, showing unbalance values directly in grams and degrees. The system also allows switching between light and heavy modes even after the rotor has stopped.

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.

When clients purchase either a balancing or wear testing machine, they gain access to comprehensive services that cover spare parts supply, operator training, on-site guidance, fast repairs, and upgrade options. These services are meant to minimize downtime and keep the balancing and wear testing equipment running smoothly all year around.

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.

Every wear tester goes through careful calibration and inspection in line with standards like ISO 9001. This step makes sure the measuring accuracy is verified and consistent before the tester is shipped out to clients.
