Installation Rotation Direction of Rotary Joint

Facing the end face of the roller shaft head, if the roller rotates clockwise, also known as right-handed, the connecting thread of the roller will be machined as left-handed. Choose the left-handed rotating joint, left-handed internal thread, and left-handed external thread.
Facing the end face of the roller shaft head, if the roller rotates counterclockwise, also known as left-hand rotation, the connecting thread of the roller is machined to right-hand rotation. Choose the right-hand rotation joint, right-hand internal thread, and right-hand external thread.
The rotation direction of the threaded connection type outer pipe and the threaded fixed type inner pipe should be opposite to that of the roller. When the rotating joint rotates, friction torque will be generated on the dynamic sealing surface. Under the action of friction torque, the connecting thread will become tighter as it rotates, otherwise, the sealing thread may fall off.
