What is hydraulic rotary coupling?

Hydraulic rotary coupling which can get hydraulic from stationary part to rotating part when 360°continually rotating, at the same time, all pipes and electrical wires is not twisted. rotary coupling are used for conveyor systems,custom machinery,fabrication equipment,rotating platforms,rotational molding equipment,welding machinery,winding machinery,amusement rides,food processing machinery,injection presses,intelligent machinery,laminating equipment,pallet wrappers,paper processing machinery,plating machinery,position welding equipment,robotic welding equipment,rotary casting machines,rotary index tables and so on.

10A and signal(5A) can be combined in any way as you need,Max.ring: 96 rings, Can be customized based on standard slip rings,Please contact us.
