    Vertical Balancing Machine

    Hard-bearing balancing machine for workpiece with diameter of up to 500mm and weight of 3-50kg

    Available in three configurations, these vertical hard-bearing machines adapt to different balancing requirements. The standard version is generally used for basic unbalance calibrating tasks, the A type includes a bench drill for material removal, and the B type combines a bench drill with a dust collection system, which is suitable for production lines that need both efficiency and cleanliness. Thanks to the integrated electromechanical structure, rotation, measurement, and braking are carried out in a single cycle, making the balancing process simple, efficient, and reliable. During use, the workpiece is mounted, the cycle begins with a single command, measurements are taken as it rotates, and the system stops automatically to deliver accurate results.

    Applications

    Widely applied in automotive and machinery workshops, to handle the balancing of common disc components, including clutches, flywheels, pulleys, gears, and brake discs.

    Specifications
    Workpiece weight 3-50kg
    Max. workpiece diameter (with safety guard) Ø500mm
    Max. workpiece thickness (with safety guard) 120mm
    Max. initial unbalance of workpiece < 1000g.cm
    Couple unbalance interference ratio ≤1/2000
    Balancing speed 800r/min
    Min. achievable residual unbalance (eMar) 1g.mm/kg
    Unbalance reduction ratio (URR) ≥90%
    Features
    • Equipped with either an embedded measuring system or an industrial PC system. Operators only need to enter basic parameters of the correction planes before starting, and the system displays the size and phase of unbalance once the rotor begins to spin.
    • A computer-based display system provides results in both numeric and polar coordinates, along with functions such as tolerance evaluation and balancing speed display.
    • Uses proximity sensors for reference signals and piezoelectric sensors for vibration signals, improving reliability compared to older sensors that were prone to weak signals, interference, or frequent faults.
    • The measuring and control system is built as a single unit, ensuring high overall accuracy and stable operation.

    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.
