Balance & Test Machinery Group
We design and build dynamic balancing machines for rotors: reliable, accurate and built to last by experts. Standard machines are adapted to each customer's requirements, for pump, fan, motor and automotive makers. Installation and operator training are included, with support from the UK, USA, Spain and Germany. We also test equipment such as various straightening machines and test stands for rotating systems.

Products & solutions
Three product families.
Standard machines, modified and adjusted to each customer's exact requirements.
Balance
Precision balancing that ensures optimal performance and reduces wear and tear on your equipment.
Straighten
Each machine measures runout, calculates the correction and applies it under PLC control, with minimal manual intervention.
Test
Test stands, built as complete test systems, designed to accurately evaluate your product and streamline the testing process.
UltraX measuring system
Clear. Quick. Repeatable.
Our fifth-generation measuring system. Dedicated UltraX electronics measure unbalance with extreme accuracy and connect over Ethernet to the UltraX balancing software: a clear, simple answer for operators, and every reading, setting and signal for engineers.
01 / 08
Each correction plane has its own polar display, with the unbalance amount, angle and correction shown in large, easy-to-read figures. The scale sets itself automatically, or with a single tap.
