When rotating analyzers balance a rotor, first they have to decide that the two general types of dynamic balancing machines, which one has the acceptance in their type of products or rotors, flexible or rigid, and precise in requirement
In general, if you have a small rotor to be balanced, soft bearing is the top
choice since the precise is extreme among all the balance machine. It’s like that the rotor is pendulum suspension measured that even a tiny vibration can be detected by sensor. For example, soft bearing horizontal balancing machine for JP Balancing Machines, the ring rotor is rotating on the spindle fixed by the pneumatic clamping. A 1mg unbalance weight can be located on the plane scale on screen. Moveover, soft bearing machines always have high rotating speed especially on a vertical spindle. The rotor boost fast and brake fast. Productive enhanced. Beyond this, soft bearing machines are portable and convenient to take.
