Rotary Joints
Rotary Joint / Rotary Union
A Rotary Joint, also known as a Rotary Union, is a precision-engineered mechanical device designed to transfer fluid from a stationary supply line into rotating equipment while maintaining a reliable, leak-controlled connection.
Rotary joints provide a continuous flow path between stationary and rotating components and can be engineered for media such as water, steam, hot oil, hydraulic oil, coolant, air, and other compatible process fluids, depending on the selected design, sealing materials, pressure, temperature, and speed.
Typical Applications
Rotary joints are commonly used in printing and paper machinery, textile machinery, rubber and plastic processing equipment, machine tools, cooling rolls, heated rolls, dryers, mixers, hydraulic equipment, steel and metal processing machinery, food-processing equipment, and other rotating process machinery.
Reliable Fluid Transfer for Rotating Equipment
BJSEAL Rotary Joints and Rotary Unions are engineered to provide a reliable connection between a stationary fluid supply and rotating machinery. They allow process media to continuously enter or exit a rotating component while helping maintain effective sealing throughout rotation.
Depending on the application and selected construction, rotary joints can be used for water, steam, hot oil, thermal fluids, coolant, hydraulic oil, compressed air and other compatible process media.
They are suitable for industrial equipment where reliable fluid transfer, smooth rotation, controlled leakage and long service life are important.
How a Rotary Joint Works
A rotary joint provides a sealed interface between a stationary housing and a rotating rotor or spindle. The stationary connection is connected to the plant piping or flexible hose, while the rotating section is connected to the machine shaft, roll, drum or other rotating component.
Internal sealing elements maintain separation between the process fluid and the surrounding environment while allowing relative rotation. Depending on the design, bearings support and stabilize the rotating assembly.
