Hydraulic slip ring

In many applications, the transmission of air or liquids is required beside the general electrical lines. In these cases hybrid slip rings can be used. These hybrid slip rings are often called pneumatic slip rings, hydraulic slip rings, steam rotary unions or air precision slip rings.

The hybrid slip rings contain 1 up to max. 16 media passages. Each slip ring can be equipped with M5, 1/8”, 1/4”, 3/8” or 1/2” connections. The housing is made of solid aluminium and offers maximum protection for electrical and media transmission components. For electrical transmission 6 up to 96 rings can be used for each slip ring.

For electrical transmission hybrid slip rings combine the best advanced fiber brush technology and precious metal or gold-to-gold multi-contacting, they offer low electrical noise for high data rate field bus transmission, low contact pressure for long lifetime and they are maintenance free.

We offer standardized & modularized design and fully customizable products according to the special requirements of customers in different applications.
