- 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
SMART is described as unidirectional, intended for processes without reversal or where the machine supplies a direction signal.
No. That is a portfolio-level limit; the page also lists lower-range variants. Match speed range and stand-off distance to the selected model.
It measures length and speed without contact in winding and conveying processes. Sensing and evaluation are integrated in the sensor head.
±0.05%, at 2σ for lengths above 10 m or 3σ above 20 m. Repeatability of ±0.02% of reading does not replace the accuracy definition.
S1/120 is documented up to 1 m/s at 120 mm stand-off. S80/240 is documented up to 80 m/s at 240 mm. Select for speed and installation distance.
IP67 applies to the sensor head. Counter or controller ratings are separate: IP51 front and IP20 rear. Select protection for each component separately.
