Keeping the world rotating

Rotating unions must accommodate a broad range of materials, viscosities, temperatures, pressures and speeds.

Coolant unions for machine tools

Coolant Unions must deliver high pressure coolant for Through Spindle Coolant applications. Some require transmission of air and MQL.

Steam joints and siphons for paper

Steam Joints and Stationary Siphons have been pioneered by DEUBLIN for high-speed machines.
Paper Machine applications also include steam joints for Yankee dryers, water unions for calender stacks and various other applications.

Electrical slip rings for power and/or signal

Electrical Slip Rings utilize next-generation technology for optimal, long-term operation and unrestrained transmission of power.
DEUBLIN provides an integrated hydraulic union and slip ring assembly with up to 60 channels.

Multipassage Rotating Unions

By using special plastomeric seals DEUBLIN Multi-Passage Soft Seal Rotating Unions can be used in the widest variety of applications and media.

Welcome to our info-site, thank you for your interest in Rotating Unions

Rotating Unions are a component used in machines to transfer fluids such as air, water, heat transfer oil, hydraulics, coolant or even vacuum from stationary supply lines into or through rotating machine parts found in various industries and manufacturing processes.

The technical features, the design principle and the quality in manufacturing a rotating union have device influence on machine function, its service life or maintenance intensity.

In general, rotating unions are also referenced as rotary unions, rotary joints, swivel joints, rotary couplings are sometimes, in view of the applications, as steam joint.

The name “the DEUBLIN” has become synonymous with the rotating unions.
