Structural Features: The outer tube body is directly connected to the roller or drying cylinder, and is the main rotating component with a finely machined spherical surface of the outer tube body. The bottom cover and the impregnated graphite spherical sealing ring together form a dynamic sealing friction pair with reliable sealing. The spherical sealing ring slides in the annular space in the shell. In addition, the oil-free bearing and the shell closely cooperate. The rotary joint is free to support, so the installation accuracy is not high. After the spherical sealing ring is worn, it can be compensated at any time with the help of the pre-pressure of the spring. During the compensation, the housing slowly moves backward and can pass through the outer tube body. The degree of wear of the seal is observed on the scale line. When steam, water or other mesons flow through the spherical sealing ring and the oil-free bearing, a very thin liquid film is formed to provide sealing and lubrication.
Thereby reducing friction and wear and extending service life.

Structural features The outer tube body is directly connected to the roller or drying cylinder, and the spherical surface of the outer tube body has been precisely processed for the main rotating parts. .

Thereby reducing friction and wear and extending service life. In addition, double lug support is used on the shell to make the support of large-scale rotating joints more stable. The seal
is more stable.
Special rotary joint for printing and dyeing
(*) Special rotary joint for printing and dyeing is specially designed and improved according to the characteristics of the printing and dyeing industry. It completely replaces the old type
in terms of performance. It is an ideal product for the printing and dyeing industry to update. According to user needs, there are siphon hoses and hard pipes inside, and special metal hose connectors outside.
