Horizontal balancing machine for Small rotors and complete assemblies
Small rotor balancing machine
  • Complete workplace designed for standing or seated operator
  • Highest balancing accuracy through super-critical support pedestals and digital meaurement processing
  • Short change-over times, simple and safe operation
  • Modular design for various applications

Range of application on this balancing machine

Universal balancing machines R1B is especially suitable for verysmall work-pieces such as small armatrues, miniature ventilators andcomplete assemblies, when high balancing tolerances at high speed mustbe achieved. They are used in small production lots as well as researchand development applications.

They can be used at varying locations and the change-over for other rotor types is possible in a short time.


Displacement measuring, horizontal balancing machines of tabletopdesign for standing or seated opertor with semi or fully automaticoperating sequence.

If the machine is to be used for assemblies, the two supportpedestals are connected by a frame. An adapter and clamping arrangementis mounted onto this frame for supporting the rotors.

The drive canbe by tangential, under slung, over slung, compressed air or, in caseof complete assemblies, by an integrated supply for self-drive.
