A Construction Machinery Rotary Union is a precision-engineered device that allows the safe transfer of hydraulic oil, water, air, or grease between stationary supply lines and rotating components of heavy-duty machinery. These rotary unions are essential for equipment such as excavators, cranes, loaders, drilling rigs, and concrete pumps, ensuring smooth operation of hydraulic systems under demanding conditions.
Our rotary unions are designed to meet the needs of construction machinery manufacturers and equipment operators worldwide. With rugged construction, high-pressure capability, and leak-proof seals, they are excellent alternatives to expensive OEM parts, offering the same performance at a fraction of the cost.
