Product Overview
This compact, flanged, two-channel air rotary joint is designed for applications requiring integrated air flow into a rotating spindle. Its flanged end mounts directly into a 15mm ID body, enabling simultaneous transmission of power and pneumatics. The housing is constructed of lightweight and durable aluminum alloy. It features two integrated M5 air ports (compatible with 6mm tubing) and supports an operating pressure of 0.8 MPa and a rotational speed of 200 RPM, making it an ideal choice for applications such as small automation equipment and rotary fixtures.
Key Features
1. Highly Integrated Spindle Connection Design
The flange-mounted design connects to a 15mm outer diameter rotating spindle, integrating the pneumatic module and drive shaft into a compact design for easy installation.
2. Compact Dual-Path Pneumatic Interface
Two M5 gas channels are provided, compatible with 6mm tubing. This meets the basic requirements for dual-path independent pneumatic functions (such as double-acting cylinder control) and is suitable for applications with limited space.
3. Excellent Dynamic Performance and Pressure Capacity
Supporting a maximum operating pressure of 0.8 MPa, it meets the pressure requirements of most industrial pneumatic systems.
A maximum rotational speed of 200 RPM indicates its suitability for medium-speed rotation and maintains reliable sealing under dynamic conditions.
4. Lightweight and Robust
The housing is constructed of aluminum alloy, ensuring structural strength and durability while achieving a lightweight design.
