What is a Hydraulic Oil Rotary Union?

A Hydraulic Rotary Union is a mechanical device that facilitates the transfer of hydraulic fluids between stationary and rotating parts of machinery. It operates by maintaining a sealed pathway that allows for continuous fluid flow while accommodating rotation, thus preventing leaks and ensuring efficient performance in hydraulic systems.

Core functions include:

  • Supplying hydraulic oil to rotating shafts or systems
  • Maintaining pressure stability under dynamic conditions
  • Supporting continuous rotation without fluid loss
  • Enhancing system efficiency and reliability
