A coolant rotary union is a device that allows for the transfer of coolant fluid between stationary and rotating components, like a spindle with a cutting tool. This is crucial for dissipating heat and ensuring proper lubrication of the cutting edge in various industrial processes.

ACROW is the famous TAIWAN machine tools accessories brand, supplies accessory for machining centers tools like Pallet Clamping Systems, Rotating Coolant Unions, Spindle Clamping Units, Measuring Instruments, High Speed Spindle Collets. Its rotating coolant unions can be widely used in in various industries, including machine tools, automotive manufacturing, and steel production, where they are essential for cooling and lubricating rotating components.
