Description
APPLICATION
The 721-11 Series is a hard-supporting horizontal dynamic balancing machine with roller bearings and universal-joint coupling drive. An industrial control computer delivers real time color display of imbalance phase, amplitude and speed. Widely used in motors, blowers, diesel engines, agricultural and textile machinery. Supports single-side, double-side and multi-plane correction for shaft, disc and centre-of-gravity rotors
