Non-Thru-Hole
The RD rotating hydraulic cylinder is a compact, lightweight, double-rod rotary cylinder. Engineered with built-in safety check valves and pressure relief valves, it ensures stable and reliable operation while preventing pressure surges.To maintain optimal performance and avoid back pressure, the drain port must be independently connected to the oil tank. This design enhances the cylinder’s durability and efficiency, making it ideal for precision rotary motion in hydraulic systems.
