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.
