Rotor where the center of gravity is located between the bearings.
Compensation for tooling unbalance and for unbalance caused by clearance and runout in the mounting surfaces between tooling and a rotor to be balanced to identify the true rotor unbalance. Therefor the rotor will be turned against the tooling between consecutive measurements.
Turning the rotor into a required angular position.
Unbalance of any kind that exists in the rotor before balancing.
Bearing system with identical dynamic properties in each radial direction.
