DEUBLIN Rotary Unions / Slip Rings

Rotary unions are widely used in various types of industrial machinery. They transfer media—such as water, oil, coolants, gases, and electricity—from a stationary source to a rotating component to achieve cooling, power transmission, and other operations. Founded in Chicago, USA, in 1945, Deublin has stood the test of time through 80 years of development to become a leading brand in the rotary union industry. Its patented mechanical seals maintain a perfect, leak-free seal under high-speed and high-pressure rotation, adapting seamlessly to the transition of various media. Industries ranging from machine tools, steel, and papermaking to plastics/rubber and semiconductors all rely heavily on Deublin’s rotary union products.

An electrical slip ring is a device that allows the transmission of power, signals, or data from a stationary source to a continuously rotating piece of machinery. It is available in a variety of configurations, connection methods, and materials to suit most applications. The core design criteria include signal or power transmission technology, interface connection methods, operating speed, and ingress protection (IP) ratings. Slip rings are applied across a wide range of fields, including wind power generation, semiconductors, plastics, construction, food processing, and intelligent robotics.
