- 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
Yes. It is a bidirectional length and speed sensor with direction recognition, standstill detection and measurement from 0 m/min.
The manufacturer lists quadrature output or ASCII over a serial interface, with Ethernet and industrial-bus options depending on configuration.
It measures moving-material linear speed and length by laser Doppler sensing, without a measuring wheel or special material markings.
Typical ±0.05% accuracy is specified at 2σ for lengths above 10 m or 3σ above 20 m. Repeatability of ±0.02% of reading is separate.
No. The listed S1, S3, S5 and S20 versions have ±1, ±3, ±5 and ±20 m/s ranges respectively. The family maximum is not every model range.
