Rotary Joint Installation Diagram

Tips: Rotary joint slip ring working principle.

Rotary joints typically include a fixture, also referred to as a housing. The housing has an inlet for receiving the fluid medium. The non-rotating seal is mounted in the joint housing. The rotor (ie, the rotating piece) includes a rotary seal and an outlet for delivering fluid to the rotating assembly. In a rotary joint, the sealing surface of the non- rotating seal is typically biased by a spring, medium pressure or other means, then form a sealed connection with the fluid on the sealing surface of the rotating seal. The seal allows the fluid medium to be transported through the rotary joint without significant leakage between the non-rotating portion and the rotating portion.

Sorry, we only have the rotary joint with G1/8" port size (ATO-3002006-24S, ATO-3002006-2405), 2-passage rotary Air & 24-wire 2A connection or 24-wire 5A connection. See https://www.ato.com/2-passage-rotary-joint.

Do you have any other ring connection types/sizes?

The ID of my tubing is 3/16". Do you have any other connection types/sizes?

ATO Responded

In model number ATO-RTJT-3004, stainless steel material can be customized. But we also need to confirm the following specifications:
1. You need to indicate the required Number of Signal Wires.
2. Connection types/sizes are available: G1/8, G1/4, G3/8".
Which connection size do you want to choose?
And what is the pressure of the oil pipe?

Can you provide a budgetary estimate of slip ring?

I'm looking for a slip ring/rotary union similar to this product customized to have additional lines in it.
The unit would need a total of:
Power - 6 lines (10A)
Data - 36 lines (2A)
RS232 and ethernet communication
4 Pneumatic lines
If this product can be configured for this, can you provide a budgetary estimate?
If you need additional information, please let me know.

We can provide customization, but we also need to confirm the following information:
1. Is the quantity of RS232 and ethernet communication one set each?
2. The RS232 communication cable is two-core +1 shielded, so is the Ethernet communication a Gigabit or a 100M cable?
Please tell us what are the specific specifications of the communication cable.

Working temperature

Can the pneumatic rotary joint withstand 70°C? I'm building housing to insulate the unit, wondering if I need to replace the joints on the hot side. Is it waterproof?
