Description of 3404004 Hollow Shaft Slip Ring
SENRING 4 passage Hollow Shaft Rotary Unions 3404004 series is 4 in 4 out hollow bore rotary union, standard hollow shaft size 20mm, other hollow shaft sizes can be customized.
What is a slip ring on a shaft?
The slip ring rides along a center shaft and sits on a base plate. The base plate or mount is held stationary and the shaft rotates in the center. This allows the slip ring to transfer power from a stationary system to a 360-degree rotating unit, completing the circuit.

FAQ:
1. Are you a factory or a trading company?
A: We are a professional manufactory with High-level R & D team.
2. What is a slip ring?
A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. A slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals. It can improve mechanical performance, simplify system operation and eliminate damage-prone wires dangling from movable joints.
