DEUBLIN Slip Rings - Slip Rings and Slip Ring Units
Electrical Slip Ring Products


DEUBLIN is the leading manufacturer of rotating unions for use in the industrial sector and wind power industry. Building on decades of experience in the implementation of sophisticated rotating union applications, DEUBLIN has developed electrical slip rings in such a way that they meet the requirements of today’s demanding environments.

The electrical slip rings use the newest technology in order to guarantee long-term operation and a reliable connection of signalling and power.

DEUBLIN slip rings were developed in order to meet the demands of industrial manufacturers for a longer operating lifespan. The integrated system was optimized with the help of special material configurations which are designed to enable a hundred million of rotations, whereby long-term smooth operation at high capacity is achieved. What is most important for DEUBLIN during the development phase is high reliability which significantly reduces downtime and maintenance costs.


Slip Ring

As with all DEUBLIN products, our slip rings are 100% tested before being used operationally and they are manufactured using the most modern of manufacturing processes. Durable technology ensures constant and reliable performance and maintenance-free operation.

Slip Ring Data Sheets



An electrical slip ring acts as an electrical connection, allowing the transmission of electrical power (current), signals or data from a stationary device to a rotating machine. It provides a physical contacting method for power or data transfer, replacing cables, which would twist and eventually break, in rotating devices.

An electrical slip ring consists of five main components – the brush (sliding contact), conductor ring, ball bearings, rotor, and housing. The fixed brushes make a sliding contact with the conductor ring, creating the rotating electrical connection. The conductor ring mounts on the rotor. Lead wires, which are attached to the brush and conductor ring internally, provide the electrical connections to either side of the slip ring. External electrical connection options include lead wires, connectors, and terminal blocks. Slip rings are available in a variety of sizes - typically ranging from less than one inch to several feet in diameter, channel counts, termination types, and materials. In general, the smaller the size of the conductor ring, the less wear on the sliding contacts, which extends the life of the slip ring. However, in some cases, a larger conductor ring is required to allow media, such as fluids, to pass through the center via a hose or tubing. Slip rings can be mounted with a flange, threaded rotor, slip fit over a shaft or into a shaft cavity.
