ZL-210
Hard.bearing balancing machine for shafts, rotors, and elongated components used in motors, pumps, fans, and industrial applications
Automatic horizontal balancing machines combine high detection accuracy, reaching levels below 1 g, with fully automated processes. They handle measurement and drilling for unbalance correction without manual work, improving productivity and lowering operating costs.
Applications
Widely used for shaft-based and elongated components. They are suitable for measuring and correcting unbalance in:
- Electric motor rotor balancing
- Impellers balancing
- Brake drums balancing
- Flywheels balancing

| Electronic measuring system/control cabinet | ZL-210 dynamic balancing measuring system (touch screen)/free-standing control cabinet Calculates the required correction weight and its position on the rotor’s left and right planes, based on parameters such as diameter, mass, operating speed, and balancing accuracy |
| Min. achievable residual unbalance (eMar) | ≤0.5 |
| Unbalance reduction ratio (URR) | 95% |
Features
- The drive motor uses a flat belt placed at the rotor’s center to keep rotation smooth and stable during testing.
- An integrated drilling unit, controlled by PLC, moves across an 800 mm range on the beam with a 20 mm drill bit to perform unbalance correction directly above the workpiece.
- Once measurement is complete, the drill automatically stops at the correction point, removing material on both balancing planes.
- Drill depth is calculated after selecting the bit diameter and the density of the material, improving correction accuracy.
- A printer is included for generating A4 reports of the test results.
- An industrial vacuum system is provided to collect chips from the drilling process, keeping the workspace clean.
