Virio
Vertical balancing machines from the Virio series offer you maximum flexibility for all workpieces without their own shaft journal. Whether very small or large rotors up to 300 kg, single or small series production:
with Virio, you can balance with precision.
with Virio, you can balance with precision.

The right spin for your rotors
Perfectly balancing disc-shaped rotors Virio vertical balancing machines are ideal for disc-shaped or pot-shaped rotors without their own shaft journal, such as belt or brake discs, pump impellers, fans, clutches, and flywheels. The arrangement of the clamping elements directly on the precision spindle means that no special auxiliary shafts are required, and the rotors can be quickly stored in a workpiece holder. The advantages for you: less time required and more efficient workflows.

Permanently calibrated: Balancing made easy All Virio balancing machines are permanently calibrated. This makes balancing a breeze: simply insert the rotor, enter the geometry data, start the measurement run, and perform the balancing. The unbalance for one or both balancing planes is displayed during the first measurement run – time-consuming calibration runs are a thing of the past. This way, you can achieve perfectly balanced rotors reliably and with just a few balancing steps.

Flexible investment in the future The state-of-the-art and flexible Virio balancing system impresses every day in your workshop and production use with its high practical value. Thanks to numerous well-thought-out details, you can quickly and economically achieve perfect balancing of your rotors. In addition, Virio can be flexibly adapted to a wide variety of balancing tasks – from manual solutions for workshops and repairs to integration into series production.
