Rotary joint is also known as rotary union, is a type of conductive slip ring. Common products are hydraulic rotary joint, pneumatic rotary joint, and electrical rotary joint. Rotary joints are available in 2~24 passages of gas/flow, can match with corresponding circuits quantities and current, support 4mm, 6mm, 8mm, 10mm, 12mm pipes. The threaded connections are M5 and G1/8. Rotary joints not only transmit gas and liquid at 360° rotation, but also mix transmit currents and signals. Transportable medium include compressed air, steam, cooling water, hot oil, vacuum, and the like.
1-passage rotary joint is a kind of slip ring. It supports M5 port for 4mm pipes, can transfer various mediums including hydraulic, cooling water, compressed air, steam, vacuum, negative pressure, positive pressure, hot oil, etc. When 360° rotating, it also can combine to transmit electrical power and signal.
The 2-passage rotary joint has G1/8" port for 6~8mm pipes, can be used in transmission for various gas and flow mediums such as compressed air, steam, vacuum, pressure, cooling water, hot oil, etc. In 360° rotation, it also can combine to transmit electrical power and signal.
The 4-passage rotary joint are ideal for 360° rotation transmission of 2A~800A current and 2A~10A signal. The 4 passages with 4 inlet and 4 outlet to make flow of the same or different medium into or out of the rotating equipment. The medium can be compressed air, steam, vacuum, negative pressure, positive pressure, cooling water, hot oil, etc. Its thread port is G1/8" for 6~8mm pipes, can be integrated directly with slip rings.
The pneumatic rotary union has 6 flow/gas passages with 6 inlet 6 outlet and the 6 passages do not interfere with each other. It can transfer various medium including air, water, hydraulic, vacuum and the like. It has G1/8" thread port suitable for 6~8mm pipes. It not only can transport gas and liquid, but also current and signals.
The electrical/pneumatic rotary unions have 8/12 passages to select, can transfer hydraulic, air, steam, oil and other fluid medium. It is 8/12 inlet 8/12 outlet, not only transport gas and liquid in 360°, but also transmit current/signal. The thread port is G1/8" and M5, support 4~6mm and 6~8mm pipe. The rotary joint is light in weight, small in size and small in torque, and the each passage do not interfere with each other.
