CENO design and manufacture various integrated slip rings for our customers in past twenty years, slip rings are applied to different areas and mechanical equipment etc. Take the Power Pneumatic Hydraulic slip ring for example, it’s often used in the large electric excavator.

As we know that the Power Pneumatic Hydraulic slip ring is a kind of special Rotary Union that can transfer the gas, liquid and electrical signal. It’s widely apply to kinds of rotating equipment. It’s working principle is to transmit gas, liquid and electrical signals between the rotating part and the fixed part by sliding contact.

The Power Pneumatic Hydraulic slip ring consists of a Rotor part and a Stator part. The Rotor part usually consists of bearings, rotor and seals. While the stationary side consists of the housing, seals and terminals. When the rotating part turns, the gas and liquid enter the rotating part through the seal, and then transfer to the fixed part through the bearing and rotor. Electrical signals are transmitted through the terminals.In addition, we also have a series of gas-hydraulic slip rings used in various automation equipment.
