ROTARY UNIONS :

Hydraulic Unions Rotary Joints, also known as

rotary couplings or Swivels, are a mechanical device used to transfer fluid (usually hydraulic oil) 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.
