After placing an order, the shipment of Balanset-1A or Balanset-4 usually occurs within a few business days. Delivery time can vary depending on your location and chosen shipping method. For more precise information, it is recommended to contact our support service.

Balanset-1A and Balanset-4 devices come with a 1-year warranty. In case of technical problems during the warranty period, we will provide repair or replacement of the device.

Balanset devices are known for their high quality and reliability. Breakdowns are rare and most often associated with improper use of the device. With all operating conditions met, the likelihood of a breakdown is minimal.

If the device breaks during the warranty period, you need to contact our support service to organize repair or replacement of the device. After the warranty period expires, we offer paid repair services.

Yes, you can upgrade your old balancing machine by installing our measuring system on it. This will improve the accuracy and efficiency of the balancing process.

When facing a situation where the balancing device shows incorrect values or does not perform balancing properly, attention should be given to checking mechanical problems, ensuring proper installation of sensors, and eliminating external influences. Consider checking bearings, rotor mounting, sensor installation, and identifying resonant frequencies.

If the device shows stable values while rotating but changes after stopping and restarting, the presence of water or granular material in the rotor could be the reason. Such materials can change the center of mass, creating imbalance. Check the rotor for water or granular materials and clean or dry as necessary.

This often happens when the equipment operates at a frequency close to its resonant frequency, amplifying vibrations. To solve this, check the operating frequency, consider equipment retuning, or use damping devices.

Ensure the correct direction of weight addition as per the device's recommendations. Check the stability of readings in vibrometer mode and for any mechanical problems such as bearing wear or rotor misalignment.

The standard set includes everything necessary for balancing except for weights and a notebook. You may need additional accessories like vibration sensors, an optical sensor (laser tachometer), electronic scales, and a magnetic stand.

No, there are no monthly payments required when purchasing a Balanset device. You pay for the device and selected accessories once with no restrictions on use.

Any notebook with a Windows 7 or higher operating system will work with the device.

The software for Balanset devices is available in English and Russian.

Yes, our Balanset-1A device is suitable for balancing a wide range of rotors, including Crushers, Fans, Cardan Shafts, Centrifuges, Turbines, Shafts, Pulleys, Electric Motor Rotors, Pumps, Compressors, Propellers, Mulchers, Combine Harvesters, and many other types of equipment.

Balanset-1A is a two-channel device for balancing rotors mounted on two bearings, suitable for equipment such as crushers, fans, augers, etc. Balanset-4 is designed for balancing rotors, such as cardan shafts, mounted on four bearings, and can also be used for rotors on two bearings. Arbalance is a two-channel portable device for balancing that does not require connection to a notebook.

If the tachometer does not read values, check whether it is too far or too close to the reflective mark or whether the laser path is obstructed. Try placing the tachometer at a different angle. Ensure that there is a clearly visible reflective mark on the surface of the rotating object and that the tachometer is correctly set to detect it. Make sure there are no reflective elements on the rotor that could be recognized by the tachometer as a reflective mark.

The rotor may have unstable rotations. In the software settings, find the item "Unevenness" and set a higher value. The tachometer may catch reflections on the rotor. Place it at a different angle, find a place for the reflective mark where the laser will not catch reflections.

Before conducting balancing, ensure:

  • Rotor Attachment: The mechanism is securely attached to the foundation without any play.
  • Bearing Condition: Bearings are inspected for wear or damage as faulty bearings can introduce additional vibrations. Bearing play is a frequent issue.
  • Sensor Functionality: All vibration and tachometer sensors are operational and correctly installed. Avoid mounting sensors on unstable structure parts.
  • External Factors: There are no external vibration sources that could affect measurements, such as other rotating machinery on the same frame.
  • Casing Integrity: The mechanism's casing is free from cracks.
  • Resonant Frequencies: Identify resonant frequencies as balancing at these frequencies is not feasible.

Common errors and their corrections include:

  • Structural Resonance: Check for resonant frequencies by altering the rotor speed and observing vibration changes. Strengthen or modify the structure to shift its natural frequencies if necessary.
  • Faulty Bearings: Replace worn or damaged bearings to reduce vibration.
  • Foundation Attachment: Ensure the rotor is securely fixed to the foundation, tightening all fastening elements appropriately.
  • Rotor to Structure Clearance: Verify sufficient clearance between the rotor and stationary parts to prevent contact-induced vibrations.
  • Shaft Straightness: Use dial indicators or suitable methods to check for shaft misalignment or bending, correcting as needed.
  • Tachometer Stability: The tachometer should be firmly mounted to avoid movement during measurements.
  • Correct Weight Placement: Ensure weights are placed accurately according to device indications for effective balancing.
  • Removal of Trial Weights: Always remove trial weights after each balancing step to prevent incorrect readings.

The test weight mass is calculated using the empirical formula:

MA = (K * Mp) / (RA * (N/100)^2)


  • MA - test weight mass, in grams (g)
  • Mp - balanced rotor mass, in grams (g)
  • RA - test weight installation radius, in centimeters (cm)
  • N - rotor speed, in revolutions per minute (rpm)
  • K - coefficient from 1 to 5, considering the conditions of the balanced rotor installation.
