pneumatic rotary union for air

Pneumatic rotary union for air is a mechanical device used to transfer gas between fixed pipelines and rotating parts. It is widely used in various types of rotating machinery, such as turntables, winding equipment, packaging machines, printing equipment, etc.

Advantages

1. High reliability sealing structure
The pneumatic rotary joint adopts imported Viton fluororubber sealing ring in the sealing design, which has good high temperature resistance and chemical corrosion resistance, and is suitable for a variety of gas medium environments. At the same time, its sealing surface is processed by high-precision grinding, and the surface roughness can reach Ra≤0.4μm, which effectively reduces the risk of leakage.

2. Support high-speed rotation
The rotating structure of this product adopts double-row deep groove ball bearing or sliding bearing support, so that it can maintain good mechanical stability during rotation. The maximum rotation speed supported by the product design can reach 300 rpm, and the specific speed depends on the number of channels and the air source pressure. In order to further improve the operation accuracy, the product controls the axial runout better than 0.02 mm, which can effectively reduce the vibration and wear during the rotation process, and is suitable for automation equipment or robot arm systems with high requirements for rotation accuracy.

3. Multi-channel design
The rotary joint supports multi-channel structure configuration, and generally provides standard options of 2 channels, 4 channels and 6 channels, and can also customize the number of non-standard channels according to customer needs. Each channel adopts an independent sealing structure to ensure that the gases between channels will not interfere with each other. In actual tests, the probability of internal cross-flow is less than 0.001%.

4. Corrosion-resistant and high-strength material
The main material of this product can be selected according to the usage scenario, including high-strength carbon steel (black surface anti-rust treatment), aluminum alloy (anodized treatment) and stainless steel (such as 304 or 316). These materials have good mechanical strength and corrosion resistance. The compressive strength of carbon steel is not less than 320 MPa, which is enough to withstand the workload generated in conventional pneumatic systems.
