- Axle Drives With our balancing machines for front and rear axle transmissions, the measured unbalance is corrected by drilling into the drive flanges of the transmissions (welding optional). We support you with our interdisciplinary expertise in the production of front and rear axle transmissions from the initial idea to the design stage through to series production.

Frequently asked questions
Answers to the most common questions about our products and services
The selected magnet determines the range; the manufacturer describes 20–55 mm options using different specified magnets.
No. Its continuous linear distance signal supports displacement measurement rather than only presence detection.
Yes. It measures distance to a suitable target magnet. Match magnet to range and geometry rather than assuming all magnets provide identical performance.
The manufacturer describes measurement through non-ferromagnetic materials such as aluminium. This does not establish suitability through ferromagnetic steel.
No. It measures the magnet without contact. Install magnet and sensor so distance and motion remain within the selected configuration.
