What is a Hydraulic Rotary Union?

A hydraulic rotary union (also known as a rotary joint, hydraulic swivel, or rotating coupling) is a precision-engineered mechanical device designed to transfer pressurized hydraulic fluid between stationary and rotating components in machinery. It ensures leak-free, continuous fluid flow while accommodating rotational movement, making it indispensable in applications where dynamic motion and hydraulic power transmission…
