Detailed information
Application examples
Deublin rotary unions for cooling lubricants are designed for a long service life. However, as they are installed deep inside a machining centre, it can be difficult to judge when a worn rotary union needs to be replaced. The SpindleShield® technology protects the spindles against coolant ingress by warning the machine operator of any unusual leaks.
