The HA series air rotary joint is a single channel sealed rotary connection device designed specifically for compressed air/gas media. It adopts a balanced sealing structure and carbon graphite/silicon carbide friction pair, supports dry operation, and is widely used in pneumatic fixtures, rotary cylinders, and automation equipment

Product Features
The HA series air rotary joint is specially designed and developed for mechanical equipment with compressed air, vacuum, oxygen and other gas-liquid media working conditions. It adopts a balanced mechanical seal structure to effectively reduce friction coefficient and wear. Anodized aluminum alloy shell, imported precision bearings, lightweight and compact aerodynamic design, various sealing combinations of carbon graphite, silicon carbide (ceramic), tungsten carbide (alloy), and tool steel can be applied to complex and complicated working conditions such as high speed, high pressure, low speed and high torque. There are also large diameter, high flow, maintenance free self-lubricating bearings specially designed for air clutches and vacuum suction cups, with high service life and reduced downtime for maintenance.
Single channel design, self-supporting rotary joint, radial shell connection, balanced mechanical seal, seal combination: carbon graphite/quenched tool steel or carbon graphite/silicon carbide, sealing chamber felt for air medium, oil nozzle for lubrication (3 to 5 drops per month), low torque design, weight optimization design, aluminum shell, stainless steel or carbon steel rotor, depending on the model, lifelong lubrication ball bearing

1、 Excellent sealing performance
The HA series air rotary joint adopts advanced sealing technology and high-quality sealing materials, ensuring zero leakage transmission of gas media under high-speed rotation and high-pressure conditions. Its unique sealing structure design effectively prevents foreign objects such as dust and impurities from entering the interior of the joint, reducing the wear of the seal and greatly extending the service life of the rotary joint. Whether in industries with extremely high hygiene requirements such as food processing and pharmaceuticals, or in areas with harsh working conditions such as chemical and steel industries, the HA series air rotary joints can operate stably and reliably with excellent sealing performance, providing a solid guarantee for the production process.
2、 Efficient fluid transmission efficiency
The internal flow channels of this series of rotary joints have been carefully optimized to minimize the resistance of gas passing through the joints, ensuring efficient fluid transmission. In some production processes that require strict gas flow and pressure, such as pneumatic conveying systems and pneumatic actuators in automated production lines, the HA series air rotary joints can quickly and stably transport the required amount of gas, effectively improving production efficiency, reducing energy consumption, and saving production costs for enterprises.
3、 Widely applicable fields
The HA series air rotary joint has strong adaptability and can be widely used in various industrial scenarios. In papermaking machinery, it can meet the gas supply requirements for components such as drying drums and calendering rollers during the paper production process, ensuring the dryness and flatness of the paper; In the field of packaging machinery, providing a stable air source for the rotating parts of various packaging equipment to ensure the precise execution of packaging actions; In printing equipment, reliable transmission of compressed air meets the process requirements of cleaning the printing drum and inflating the inflation shaft, ensuring the stability of printing quality. In addition, HA series air rotary joints play an indispensable role in production equipment in industries such as textiles, rubber, and plastics, providing strong support for efficient production in these industries.
