The importance of static sealing gasket sealing for rotary joints

The poor sealing of the static sealing gasket between the shoulder of the rotary joint cup sealing sleeve and the inner wall of the roller is caused by both material and manufacturing accuracy errors.

The material requirements for the static sealing gasket of the rotary joint are heat and water resistance, and the quality requirements are average thickness and smooth surface.

The shoulder of the cup shaped sealing sleeve of the rotary joint not only needs to have a certain degree of stiffness, but also its verticality and surface smoothness with the axis of the rotary joint are important.
