What is a Deublin 902 Series Rotary Union?

The Deublin 902 Series rotary union is a multi-passage mechanical device used primarily to transfer fluid—such as coolant, MQL, or air—from a stationary source to a rotating component, most commonly the spindle of a CNC machine. Its design is crucial for high-speed machining operations, as it allows for the continuous and efficient delivery of fluid to the cutting tool, helping to cool, lubricate, and clear chips.

Our rotary joints handle the high speeds and pressures typical in modern machining, ensuring a leak-free seal and long-term, dependable operation.
