4 Passage Hollow Shaft Rotary Unions M5 Support 4~6mm Pipes
Standard Hollow Shaft Size 20mm
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.
3. Do you offer custom slip rings?
Yes, if you are confident that a custom / modified solution is most
likely required or need assistance in your selection, contact us to
Get Started. Our engineers will come up with the perfect solution
for your needs.
