Pinion Rotary Hydraulic Cylinder
Pinion Rotary Hydraulic Cylinder Swing Hydraulic Cylinder with Rack Gear Rotary Telescopic Hydraulic Cylinder for ship Advantages of Rotating Hydraulic Cylinder for Hot Strip Rolling These robust actuators excel in hot rolling mills by converting linear hydraulic force into precise rotary motion (90°-270° swing). Their gear mechanism delivers 5,000-50,000Nm torque with ≤0.1° positioning accuracy, critical for coil transfer cars and descaling spray rotation. The hardened alloy steel rack withstands 200°C+ temperatures and scale contamination, outperforming vane-type actuators in dirty environments. Maintenance is simplified through modular gearbox access without dismantling hydraulic connections. Key benefits include 20% faster index times versus chain-driven systems, continuous 360° rotation capability (special designs), and IP67 protection against coolant ingress. Their rigid construction prevents deflection during heavy coil handling (up to 50-ton loads), while standardized mounting…
