Multiple Solutions for Multiple Environements and Cable/Hose Combinations

There are heaps of cable/hose reel typologies, from simple applications for domestic use to the complex ones of harbors and offshore oil platforms.


The common link, regardless of the final application, is the use of a Slip Ring or a Rotary Union. Cable reels usually transmit power and electric signals, data and different kind of fluids; instead, in case of high-frequency signals, high data rate or where a low bit error rate (BER) is required, the proper result is achieved with a fiber optic rotary joint. Our product range can cover nearly all application from power signals to high data rate or optical signals for cables and from pressurized air to hydraulic oil for rotary union. Our standard solutions also offer simple combinations between slip rings and rotary unions when cables and hose pipes are mixed.

Facts & Figures

  • With a medium speed of 5 rpm a slip ring  (multi-wire brushes design) can operate at least 20 years without being replaced
  • Power signals and sensors or control signals (Field bus, motor encoder, etc.) can be embedded in the same slip ring
