Use of oil as a medium in rotating unions:
In machine tools and CNC machines
In machining technology, e.g. in milling machines and lathes, oil is used as a lubricant and coolant. Rotary unions allow oil to be fed to rotating spindles and tools to reduce friction, control temperature and extend tool life.
In rolling mills and pressing plants
In metal processing, especially in rolling mills and pressing plants, large rollers and presses are lubricated with oil. Rotating unions ensure that lubricating and cooling oil is continuously supplied, which increases efficiency and reduces wear on the machines.
In hydraulic systems
In hydraulic systems, such as hydraulic drives, oil is used as a power transmission medium. Rotating unions make it possible to move the oil safely between rotating and stationary components so that pressure and volume flows remain constant.
In the automotive and aviation industries
In automotive manufacturing, e.g. for drive trains, and in aviation, rotary unions are used to feed engine oil or hydraulic oil to rotating components that are subject to high speeds or temperature fluctuations.
In the paper and plastics industry
In the production of paper and plastics, machine components such as extruders and rollers are used that need to be supplied with lubricating oil or cooling oil. Rotating unions ensure that the oil is supplied effectively to control friction and heat build-up
In wind turbines
Rotating unions are used in wind turbines to feed lubricating oil into rotating gearbox components. This minimizes wear and helps to extend the service life of the gearbox and bearings in the nacelle.
Note: The applications listed are only an excerpt and are for illustrative purposes. Due to the large number of possible areas of application, not all use cases can be shown here.
Advantages of rotating unions for use with oil
Extension of the machine service life
The continuous oil supply minimizes wear on components.
Improved cooling and lubrication
Rotating unions ensure even distribution of lubricating and cooling oil, preventing overheating and material damage.
High efficiency and performance
Rotating unions are adapted to the special requirements of oil and ensure the smooth operation of machines under high loads.
Conclusion: Rotating unions for oil-based applications make a decisive contribution to increasing machine performance and efficiency and enabling a long service life.
