In general slip rings are used to transmit power, signals or data, pneumatic and hydraulic, from a stationary to a rotating platform. The transmission between the stator and rotor takes place via sliding contacts and is extremely reliable. The pneumatic rotary joints allows electrical and pneumatic lines from the device to feed through to the tool - keeping air and electrical lines on the machine from twisting.
Pneumatic Rotary Joint is mainly used for steam & water rotating syphon type mechanical equipments. Fabricated from optimum graded carbon materials these are available in 1" BSP to 6" BSP.
