Introduction

Every rotating component, be it a dental drill, a crankshaft or a turbine in a power station, needs to be balanced.
The Balancing and Diagnostic Systems division offers a comprehensive range of products for balancing rotating and reciprocating components and subassemblies - ranging from light-weight miniature rotors weighing only a few grams to heavy-weight rotors such as a steam turbine rotor weighing 400t.

Balancing is a critical step in the production process, and ensures the high quality of rotating components. This applies regardless of whether you are dealing with a one-off rotor in a repair shop or with large production volumes. Balancing will improve the quality and service life of your products, improve productivity and enhance your competitive position.
