Rotary Union for Coolant

Efficient cooling is critical to maintaining performance, precision, and lifespan in modern industrial equipment. We engineer our coolant rotary unions to ensure continuous, reliable coolant transfer between stationary supply lines and rotating components.

Whether used in CNC machine tools, steel processing, or automated manufacturing systems, these rotary unions ensure stable temperature control, reduced thermal distortion, and optimized machining performance.

What is a Coolant Rotary Union?

A Coolant Rotary Union, also known as a coolant swivel or rotary coupling, is a mechanical device designed to facilitate the transfer of coolant from a stationary source to a rotating component in machinery. Its primary function is to supply coolant—typically a liquid or gas—to moving parts, preventing overheating and ensuring optimal performance during operation.
We engineer these unions to withstand high pressures and rotational speeds without leaking, which protects the lifespan of the union and the equipment.
