Double Acting Hydraulic Cylinder 101.6x44.5x303.5mm · 模型 49292
Detailed Technical Description: Double Acting Hydraulic Cylinder Model/Type: Double Acting Hydraulic Cylinder, which is the most common and widely used type in hydraulic systems, controlling the movement of the piston in both directions (extension and retraction) by hydraulic power. Basic Dimensions: Bore Diameter: 101.6 mm (exactly 4 inches) – refers to the inner diameter of the cylinder body. Piston Rod Diameter: 44.5 mm (approximately 1.75 inches) – Diameter of the strong, dent-resistant output shaft. Stroke Length: 303.5 mm (approximately 11.94 inches or 12 inches) – The maximum distance the shaft can move outside the body. Working principle and operation: Extension stroke: Hydraulic oil under pressure enters through the extension port (Port A) into the rear chamber (Cap End) behind the piston. The pressure pushes the piston forward, causing the piston rod to extend. The oil in the front chamber (Rod End) exits in front of the piston through the retraction port (Port B) and returns to the reservoir. Retraction Stroke: The system reverses the oil flow. The oil now enters under pressure through the retraction port (Port B) into the front chamber (Rod End). Because the area exposed to pressure on the front side of the piston is smaller (due to the presence of the rod), the force generated during retraction is less than the extension force for the same operating pressure. The pressure pushes the piston backward, pulling the shaft inward. The oil exits the rear chamber through the extension port (Port A) and returns to the reservoir. Typical applications: Heavy construction equipment: excavators, loaders, bulldozers (for moving arms, buckets, blades). Agricultural equipment: tractors, harvesters (for lifting tools, moving conveyors). Industrial presses: pressing, shearing, bending. Material handling equipment: forklifts, industrial robots. Oil and gas equipment: valve actuators, control systems. Moving structures: drawbridges, dam gates, lifting platforms.
