Product Overview
This large-diameter, dual-channel, 2-inlet, 2-outlet slip ring is
designed for pneumatic connections in large, low-speed rotating
equipment. Its core advantage lies in its large 260mm inner bore,
greatly facilitating the layout of equipment central axes or
pipelines. Encased in an aluminum alloy housing, it features two
G1/8" air paths that accept 8mm air tubing and operates stably at
0.6 MPa. Its low 5 RPM design enhances sealing reliability and long
life under heavy-load, low-speed conditions.
Key Features
1. Extra-Large Diameter Design
Providing a generous 260mm inner diameter (353mm outer diameter)
through-hole clearance, this design is specifically designed for
equipment requiring large central shafts, pipes, or wiring
harnesses, providing exceptional flexibility in overall machine
layout.
2. Compact Dual Air Path Configuration
Integrated with two independent G1/8" air paths, these ports accept
8mm tubing, meeting the basic requirements for dual-path pneumatic
functions (such as supply and exhaust for double-acting cylinders
or control of two independent actuators).
3. Robust Low-Speed, Heavy-Load Performance
With a rotational speed of only 5 RPM, this design is optimized for
low-speed, high-reliability applications, ensuring excellent
sealing and long life at low speeds.
The maximum operating pressure of 0.6 MPa meets the pressure
requirements of most industrial pneumatic systems.
4. Lightweight and Rugged
The aluminum alloy housing ensures structural strength and
corrosion resistance while remaining lightweight, making it easy to
install and maintain on large equipment.

Application Scenarios
The slip ring's core advantage lies in its design combination of
large diameter, dual air paths, and low-speed robustness. It is a
pneumatic connection solution specifically designed for
slow-moving, bulky equipment with extreme central space
requirements, such as large slewing platforms and heavy rotating
furnaces. While ensuring dual-path pneumatic functionality, it also
perfectly solves the problem of connecting large components.
