Compare flow types and rotation direction, and learn how to measure pipe size threads to choose the right rotary joint for your system.
Aluminum One-Way-Flow Rotary Joints
 |
These joints have a rotating shaft with threads on one end that connect to a continuously revolving drum, roller, or other rotating equipment. Use them to transfer hot and cold materials from your supply line. Joints are for one-way flow and are meant to be used in pairs—one joint serves as the supply line while the other serves as the return line. They are a compact size for use in small air and hydraulic applications.
Right-Hand Thread—If your drum rotates counterclockwise as you face the connecting end, you should select a rotating joint with right-handed threads.
Aluminum—Joints are made of lightweight aluminum.
