Rotary Unions

Rotary Joints, also known as rotary couplings or Swivels, are mechanical devices used to transfer Liquid (usually hydraulic oil), Gas, or Particles from a stationary system, to a rotary system.Rotary Joints are used in wind turbines to deliver hydraulic fluid to the blade pitch actuators. Rotary Joints are also used in various industrial and manufacturing processes to transfer fluid.BGB have designed and manufactured two variants of joint, the "Sealed” type where the chambers are separated with specially designed seals, and the "Hydrostatic” type, that does not require seals between chambers.

As specialists in rotary applications, BGB can design bespoke packages to include slip rings, FORJ and Rotary Unions / Hydraulic joints as a one-stop solutions provider.  If your application requires approvals such as UL or ATEX let us know and we can custom design a win-win solution.
