The Rotary Joint device allows electrical and pneumatic lines from the robot to feed through to the tool — keeping air and electrical lines on the robot from twisting. The Rotary Joint has two components: fixed and rotating. The rotating component consists of the robot adaptor, tool adaptor, and a central connecting core. The fixed component is a central ring which is held stationary by a torque rod attached to a fixed part of the robot arm.

Lines are attached between the fixed component and your robot controller. As the robot moves, the fixed lines do not twist. Advanced slip ring technology is
used to pass fixed lines to the rotating component and then to your tool— so as your robot moves, electrical signals and pneumatic pressure pass from the robot to the tool preventing the lines from twisting. With many different sizes, this device can be easily integrated onto almost any robot.
