- 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
No. P25 is a 2100 mm potentiometer version; E and E830 are incremental encoders over the same range. The listed resolutions are 0.55 mm for P25 and 0.43 mm for the encoder, with separate linearity specifications.
Standard P25 uses soldering tags; CR-P25 has a 1 m integral radial cable. The digital-version table specifies a 2 m integral radial cable.
The specified maximum extension force is approximately 5 N and minimum retraction force 3.5 N. Account for this force when attaching the wire to a light or flexible part.
Its specified maximum wire acceleration is approximately 5g. Match actual acceleration and the required encoder or analog acquisition input.
Mount the housing using its holes or grooves and attach the moving part to the 4.5 mm wire eyelet. The operating temperature range is −20 to +80°C.
