- 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
These MEMS vibration-velocity sensors support applications including slowly rotating turbines, fans, pumps and generators. Nominal sensitivity is 10 mV/(mm/s) at ±10%.
VSI-10x is straight and VSI-20x has a 90° design. Connection suffix 1 denotes an M12 connector and suffix 3 an integrated cable. Straight and angled designs also use different mounting arrangements.
No. Option 01 is specified from 1 Hz to 5 kHz at ±3 dB, and option 02 from 3 Hz to 5 kHz at ±3 dB. The bands at ±10% tolerance are narrower.
It requires a 3–12 mA constant-current supply with nominal 24 V. On the M12 connector, pin 1 is signal and power and pin 2 is the return; pins 3 and 4 must not be connected.
The sensor is specified from +5 to +121 °C, but with an AC-14xx cable the range is +5 to +90 °C. IP68 is documented for a 2-hour test at 5 bar; select the appropriate connection.
