Precision Alignment & Metrology
In Situ Balancing — Static & Dynamic
Static and dynamic balancing of rotating assemblies, in place at the installation (in-situ / field balancing).
The field rule: any rotating component with access for adding or removing mass can be balanced in place — from wind turbine rotors and generator rotors to fans, blowers and impellers.
Imbalance is among the most common sources of vibration; correcting it in the field — without removal and transport — restores smooth running at the minimum possible downtime cost.
Off-site: crankshafts and propellers under 2.5 m in diameter are balanced off the installation, while ship propellers of 2.5 m and above are undertaken at shipyard facilities worldwide.
Applications
- Static & dynamic balancing
- Precision balancing

- Integrated systems
Wind turbine rotors
Rotor balancing together with the hub, in place at the installation.
Generator rotors
In-situ balancing of generator rotors, without dismantling and transport.
Fans & blowers (fan balancing)
Static and dynamic balancing of fans and blowers in the field.
Impellers together with their shafts
Balanced as a single rotating assembly.
Case studies & field applications
Balancing of impeller together with shaft
Dynamic balancing of an impeller together with its shaft, as a single rotating assembly.
