In addition UB’s dedicated team of specialists will design, develop and manufacture custom engineered systems to meet individual user requirements.
Why chose a horizontal axis machine from the UK’s leader in component balancing technology?
- Virtually all components can be balanced in this orientation.
- All Unibal horizontal axis machines balance components both statically and dynamically.
- Horizontal axis balancers accommodate rotors up to 6.00 metres long and 2.45 metres diameter.
- Machine variants are available for components weighing up to 20 tonnes.
- Horizontal axis machines provide maximum access for balancing operations.
- ‘V’ rollers or gimbal units enable components to be mounted in their own bearing.
- Belt or end-drive options available.
Hard or Soft Bearing Measurement
 Universal Balancing offers both hard and soft bearing machine variants to meet all application requirements. Hard bearing machines use force transducers to measure unbalance – providing accurate results independent of rotor mass or inertia.
Because they can be permanently calibrated and will handle high out of balance forces, hard bearing machines allow fast and accurate results to be achieved in a single run.
Soft bearing machines are ideal for balancing flexible, as well as rigid or semi-rigid parts and assemblies. They require calibration for each component to be measured, but will simultaneously determine the amount and position of unbalance in both correction planes.
Soft bearing machines also have the advantage of allowing rotor measurements to be taken throughout a greater operating speed range.
