Hydraulic swivels, also known as hydraulic rotary manifolds, are precision components designed to transfer fluid from a stationary source to a rotating piece of machinery.

With over 50 years of experience manufacturing slip rings, UEA can provide hydraulic swivel-slip ring combination units in a single self-contained, multimedia rotational assembly. Our swivels are custom-built to your exact specifications and application requirements.

UEA hydraulic swivel design concepts are refined utilizing SolidWorks solid modeling and FEA (Finite Element Analysis) to meet customer specifications. Manufacture of the hydraulic swivels begins with CAM (Computer-Aided Manufacturing). Swivels are then fabricated by state-of-the-art CNC machines, with seal grooves in either the housing or the spool, and are assembled with high-performance seals.

Quality assurance of the UEA hydraulic swivel includes complete component washing, flushing and testing with fluids that are continuously monitored for cleanliness. The swivels are clean-room assembled and rigorously tested prior to shipping.

  • Proper Maintenance of Hydraulic Swivels & Systems

    Proper Maintenance of Hydraulic Swivels & Systems

    Proper or no maintenance of hydraulic equipment can mean the difference between scrapping a machine at 20,000 hours or more instead of 5,000 hours. And because they often are located deep within the workings of machines, hydraulic swivels (also called rotating joints or rotating manifolds) usually receive little or no maintenance. A well-designed hydraulic swivel should not require much maintenance. However, if the swivel is mounted in a location where it is surrounded by hoses or tubing, short

    Hydraulic Swivel/Slip Ring Combination Unit Options

    Many buyers looking for a new hydraulic swivel/slip ring combination unit have an objective of saving money and creating an assembly that surpasses the requirements of the application but is not over-engineered. There are three main styles of slip ring and hydraulic swivel combination units.
