1-in, 8-out Rotary Joint with High-Strength Aluminum Alloy Housing
This 1-in-8-out large-aperture rotary joint features a high-strength aluminum alloy housing with a 130mm extra-large inner bore. Designed for industrial applications, it supports a working pressure of 1 MPa and features an IP51 protection rating. The unique configuration with one inlet (G1 3/8″) and eight independent outlets (G1/8″) enables stable distribution of a single main air source to multiple end devices, making it ideal for centralized air supply in heavy machinery, automated production lines, and large-scale testing equipment.
Key Features
130mm Extra-Large Central Through-Hole: Provides ample space for large cable bundles, water pipes, or mechanical shafts, enabling highly integrated equipment structures and organized wiring.
1-Input, 8-Output High-Efficiency Distribution: Single high-pressure air inlet with multiple independent outputs simplifies pneumatic circuit layout and supports multi-point, synchronized pneumatic control.
1MPa High-Pressure Bearing and Reliable Protection: Withstands working air pressure up to 1MPa with IP51 protection rating, effectively preventing dust and vertical water droplets in harsh industrial environments.
Heavy-Duty Structure for Robust Operation: Aluminum alloy casing ensures excellent structural strength and heat dissipation, with 30 RPM rotation speed optimized for low-speed, heavy-load conditions.

Wind power generation equipment: Pneumatic control signal transmission for blade pitch control systems.
Large-scale testing and simulation equipment: Supply of pneumatic power to multiple pneumatic actuators or sensors in turntables and environmental chambers.
Frequently Asked Questions
What specific components can pass through the 130mm inner bore?
This extra-large inner bore is designed for complex wiring and can accommodate multiple power cables, control harnesses, fiber optic cables, hydraulic hoses simultaneously, or serve as a passage for the main drive shaft of the equipment, enabling true "hollow unlimited rotation."
Can the 8 air outlets withstand different pressures?
The inlet pressure is from a single source. If independent working pressures are required for different outlets, separate pressure reducing valves need to be installed in the external air circuit (after the outlet connectors) for adjustment.
Does it support rotation speeds higher than 30 RPM?
This product is optimized for heavy-duty, precision control scenarios at 30 RPM and below to ensure optimal sealing life and stability under high pressure. For higher rotation speeds, a customized evaluation is required based on the specific operating conditions.
