The DS50 high-temperature rotary joint is equipped with precision sealing and durable ball milled cast iron made of spherical graphite, which has high strength and flexibility, improving the mechanical properties of cast iron. The ceramic ring is made of imported silicon carbide ceramics, which have high resistance to pressure, are not easily bent, have finer density, lower thermal expansion probability, and are more stable to use. Compared with ordinary graphite rings, the temperature tolerance is more than ten times higher

The hollow shaft of the DS series high-temperature rotary joint is connected to the roller or roll through threads or flanges, and is the main rotating component that moves synchronously with the equipment. The sealing ring, hollow shaft, and corrugated compensator together form a floating double end face sealing friction pair, which is beneficial for reducing the disadvantages of poor sealing caused by poor concentricity of the equipment. The sealing ring is made of impregnated carbon graphite, which has good lubricity, thereby reducing friction and wear and improving service life; With the wear of the sealing ring, the bellows compensator is compensated at any time by the pressure of the spring. The use of bearings not only plays a manufacturing role, but also improves rotational accuracy and reduces friction torque. In addition, there are observation holes on the shell, through which the wear and sealing condition of the sealing ring can be observed at any time. Regularly add lithium grease during high temperatures.

We can provide you with all the services from research and development, design and manufacturing to post maintenance of rotary joints. Customers only need to provide us with the product’s functions, performance, and even your idea of the rotary joint, and we can turn the product from a concept into reality. At the same time, we provide OEM services and use our core technology to design and develop new products to save you time and cost.
A rotary joint is a sealing device that connects stationary pipelines and rotating equipment, achieving leak free fluid transmission under 360 ° rotation. It allows fluid media to flow smoothly between fixed pipelines and rotating machines, and is a key component in industrial equipment
F90 swivel unions Transporting equipment components from a fixed pipeline system to high-speed rotating or reciprocating motion
Q32 swivel unions
JD40 rotary joint is a key sealing component in industrial fluid transmission systems, usually referring to a rotary connection device with a diameter of DN40 (or corresponding British caliber). As a transitional sealing device that transports fluid media (such as water, steam, hydraulic oil, thermal oil, compressed air, etc.) from static pipelines to dynamic rotating or swinging equipment
