The Coolant & Hydraulic Rotary Union / Joint is a high-precision mechanical device designed to transfer coolant or hydraulic fluid from a stationary supply line into rotating machine components. It is primarily used for effective cooling of tools and spindles as well as for hydraulic fluid power transmission in high-speed machinery.
These rotary unions are specially engineered for high pressure and high RPM applications, ensuring reliable performance, leak-free operation, and extended service life. Commonly used in CNC, VMC, and drilling machines, they help improve machining accuracy, enhance tool life, and maintain consistent cooling during continuous operations. Each unit can be customized to meet specific machine and application requirements.
