rotarX hollow shaft slip rings for power and signal transmission
Hollow shaft slip rings are slip rings with a central hollow shaft. This series is designed for mounting with a flange on a sleeve holder. This offers the customer a free interior space for connecting the rotor to a rotating shaft of the customer’s machine or for feeding through pipes or cables that are not affected by rotation.
The hollow shaft grinding rings are available with inner diameters from 3mm to 300mm. The customer can choose between slip rings with 2 to max. 144 rings and power ratings from 2A to 500A per ring.
The hollow shaft slip rings use the most advanced fibre brush technology and precious metal multi-contact.
They offer low electrical noise for fieldbus transmission at high data rates, low contact pressure for long life and are maintenance-free.
If you have special customer-specific requirements, we will be pleased to advise you in order to make the most suitable recommendation for your specification.
