Compact 5mm Gas Channel Slip Ring with G1/8" Connector and 20 Million Rotations Lifespan for Pneumatic Systems
This single-channel gas slip ring is a miniature pneumatic rotary joint designed specifically for compact spaces. It features a silver aluminum alloy housing with an ultra-small outer diameter of only 18mm and an internal gas flow diameter of 5mm. Equipped with a standard G1/8" gas connector, it is engineered for transmitting compressed air, can withstand pressures up to 1MPa, and operates stably at 200rpm. Ideal for small rotary cylinders, pneumatic grippers, precision purging devices, and similar equipment.
- 18mm Ultra-Miniature Design: With an outer diameter of only 18mm, it is one of the most compact pneumatic rotary joints available, easily integrated into space-constrained equipment such as robot joints and precision rotary tables.
- 5mm Large-Diameter Air Path: Achieves a 5mm effective gas passage within its compact 18mm volume, ensuring smooth gas flow, minimal pressure loss, and providing ample power for small pneumatic components.
- 1MPa High-Pressure Load Capacity: Supports working pressures up to 1MPa, ensuring strong pneumatic output while maintaining miniaturized design, meeting pressure requirements of most industrial pneumatic systems.
- G1/8" Universal Interface: Equipped with standard G1/8" threaded interface, compatible with most miniature tubing and quick-connect fittings for plug-and-play installation.
- 200rpm Dynamic Stability: Employs precision sealing technology at 200rpm, ensuring leak-free and low-wear performance during long-term dynamic rotation for stable, reliable operation.

At 0.6MPa pressure, the theoretical flow rate of a 5mm diameter nozzle can reach several hundred liters per minute. This is more than sufficient and has a margin of safety for most micro cylinders (e.g., 6-16mm diameter) and suction cups.
Yes. The standard model is suitable for clean, dry, and non-corrosive gases such as compressed air, nitrogen, and argon. For the transport of special gases, please confirm the compatibility of the sealing materials with us.
At rated pressure (1MPa) and speed (200rpm), using high-quality seals, the design life is typically 30-50 million revolutions. Based on continuous operation at 200rpm, this is equivalent to approximately 1000-1700 days of continuous operation time, with even longer lifespans in actual applications.
During installation, it is recommended to ensure the concentricity of the slip ring and the equipment's rotating shaft to avoid misalignment that could cause abnormal wear of the seals. Due to its small size, it is recommended to use flexible tubing connections to reduce radial force on the interfaces.
