Dynamic Balancing of rotating equipment’s at Daniel Group
Dynamic balancing at Daniel Group is the process of balancing a rotating component (such as an electric motor rotor, cooling tower fan, or pump impeller) by correcting any uneven distribution of mass while it is in motion. This ensures that the component rotates smoothly without causing vibrations, noise, or excessive wear.
In an unbalanced rotating system, centrifugal forces create oscillations, leading to mechanical stress and potential failure. Dynamic balancing involves identifying these imbalances using specialized equipment, such as balancing machines or vibration analysers, and correcting them by adding or removing material (e.g., adding counterweights or machining away excess material).
Static Balancing: Corrects imbalance in a stationary rotor. The component is balanced on rollers to ensure it doesn’t tip to one side. This is an outdated process and predominately performed prior to dynamic balancing for excessively new unbalanced rotating equipment’s
Dynamic Balancing: Performed while the rotor is spinning at operational speeds, which is necessary for components that experience imbalance due to centrifugal forces.
International Standard ISO 1940 is a widely accepted reference for selecting rigid rotor balance quality. For rotors in a constant (rigid) state, only the resultant unbalance and the resultant moment unbalance (resultant couple unbalance) are of interest, both together often expressed as dynamic unbalance.
ISO 1940 gives specifications for rotors in a constant (rigid) state. It specifies
- balance tolerances,
- the necessary number of correction planes, and
- methods for verifying the residual unbalance.
Dynamic balancing is classified into different balance quality grades based on ISO 1940 standards. These grades determine the allowable residual imbalance in rotating machinery and are critical for ensuring optimal performance and longevity.
- G16 – G40: Suitable for crude industrial applications like unbalanced pulleys, conveyor rollers, and large fans.
- G6.3: Standard for electric motors, pumps, generators, and turbines used in industrial applications.
- G2.5: Precision balancing for high-speed rotating equipment, including turbochargers, machine tool spindles, and high-performance fans.
- G1.0: Required for aerospace components, gyroscopes, and precision measuring instruments where ultra-low vibration is essential.
- G0.4 – G0.1: Extreme precision levels for medical devices, optical instruments, and micro-mechanical components.
Choosing the correct dynamic balancing grade ensures longer equipment life, reduced vibration, and energy efficiency in Dubai, Abu Dhabi, and Sharjah industries.
Dynamic balancing at Daniel Group is performed in either single-plane or two-plane configurations, depending on the size, speed, and operational requirements of the rotating component. Selecting the right balancing method is crucial for minimizing vibration, extending equipment lifespan, and improving efficiency in industries across Dubai, Abu Dhabi, and Sharjah.
Single-Plane Balancing
- Used for narrow or disc-shaped rotors, such as flywheels, pulleys, and fans.
- Corrects imbalance in a single correction plane, typically at the rotor’s centre.
- Ideal for components where imbalance forces do not change along the rotor’s length.
Two-Plane Balancing
- Required for longer rotors, such as turbines, fans, large shafts, motor rotors, blowers.
- Corrects imbalance in two planes, accounting for both mass distribution and rotational forces.
- Essential for high accuracy industrial machinery, reducing wear, vibration, and operational risks.

When does a rotating equipment need dynamic balancing in UAE?
New Equipment Installation
When installing a new electric motor rotor, cooling tower fan, blower fans, or pump impeller, manufactured and assembled.
After Repairs or Overhauls
If a rotor has been rewound, rebuilt, repaired, or had parts replaced (e.g., fan blades, impellers, or shafts), dynamic balancing is necessary to correct any introduced imbalance.
Excessive Vibration or Noise
If equipment shows abnormal vibration or noise levels, imbalance could be the cause. This is often observed through increased bearing wear, misalignment, or frequent mechanical failures.
Periodic Maintenance & Condition Monitoring
Over time, material buildup (dust, rust, grease), erosion, or wear can create imbalance in rotating parts. Regular vibration analysis can detect imbalance early and indicate when dynamic balancing is needed.
After a Sudden Impact or Mishandling
If a motor, fan, or rotor has been dropped, hit, or exposed to shock loading, its balance could be affected, requiring rebalancing.
High-Speed or Precision Applications
Equipment operating at high speeds (e.g., turbines, centrifugal compressors, high-speed fans) requires precise balancing to avoid resonance and excessive wear.

The soft-bearing machine derives its name from the fact that its supports are free to move (soft) in at least one direction, usually horizontally or perpendicularly to the rotor axis. The theory behind this style of balancing is simple: the rotor essentially behaves as if suspended in mid-air while the movements of the rotor are measured with vibration sensors to determine the unbalance of the rotor. The mechanical design of a soft-bearing machine is slightly more complex, but the electronics involved are relatively simple compared to the hard-bearing machines.
Hard-bearing balancing machines have stiff work supports (hard) and rely on vibration to interpret the unbalance in a rotor. This requires a massive, stiff foundation for the machines to be permanently set and calibrated in place by the manufacturer. The theory behind this balancing system is that the rotor is fully constrained and the forces that the rotor puts on the supports are measured. Background vibration from adjacent machines or activity on the work floor can affect balancing results. Commonly, hard-bearing balancing machines are used in manufacturing production operations where a fast cycle time is required.
