Hofmann horizontal balancing machines provide accurate readings, time after time. Their sturdy design combines the precision of piezoelectric transducers in a reliable hard-bearing support system on a solid-steel base.

Standard designs include adjustable supports and changeable bearings, enabling different rotor types to be used on each machine size. Custom and special designs, such as whip sensors for flexible rotors and side spindles for overhung rotors, are engineered to individual rotor specifications.

Hofmann horizontal balancing machines meet a wide range of requirements.
