Tie Rod Type Hydraulic Cylinder (With Double Rods - Double Acting) Size 40x20x121 mm · 模型 309588
⚙️1. Complete Specifications 👉Parameter 👉Value ✔️Bore Diameter 40 mm ✔️Rod Diameter 28 mm ✔️Stroke Length 121 mm ✔️Rod-to-Bore Ratio 70% (28mm ÷ 40mm) ✔️Type Double Rod - Double Acting ✔️Construction Tie Rod (NFPA/ISO style) 👉The 70% rod-to-bore ratio is substantial. This is typically used for applications with high compressive loads, significant side loading, or where superior column strength is required to prevent rod buckling . ⚙️2. Force Calculations ✔️Operating at a typical industrial hydraulic pressure of 210 bar (approx. 3,000 PSI) : ✔️Stroke Direction Area Force Output 👉Extension Force π × (2.0 cm)² ≈ 12.57 cm² 264 kg (approx. 582 lbs) 👉Retraction Force π × ((2.0 cm)² - (1.4 cm)²) ≈ 12.57 - 6.16 = 6.41 cm² 135 kg (approx. 298 lbs) 🚀Note: This retraction force is approximately 49% lower than the extension force due to the thick 28mm rod significantly reducing the annular area. This is a critical design consideration for your application . ⚙️3. Key Design Features ✔️A. Double Rod End Advantages 👉· Equal Force in Both Directions: Unlike single-rod cylinders, a double rod cylinder provides identical force output in both directions because the piston area is the same on both sides . 👉· Symmetrical Motion: Ideal for applications where the load needs to move the same distance and speed in both directions without speed changes . 👉· Reduced Misalignment: The dual rods provide better resistance to side loading and prevent piston rotation . ⚙️B. Tie Rod Construction 👉· High Strength: Four or more threaded steel rods hold the end caps to the barrel, providing excellent stability . 👉· Standardized Dimensions: Conforms to NFPA/ISO standards for mounting interchangeability . 👉· Serviceability: Can be disassembled for seal replacement and maintenance . ⚙️C. Heavy-Duty Rod Ratio (70%) 👉· Exceptional Column Strength: The 28mm rod provides excellent resistance to buckling under compressive loads . 👉· Side Load Capacity: Can withstand significant off-center forces, making it suitable for applications with imperfect alignment . ⚙️4. Common Applications for Double Rod Cylinders ✔️Based on standard industry practice, this specific configuration is ideal for: 👉· Precision Positioning Systems: Where symmetrical movement is required on both sides of the cylinder . 👉· Automated Assembly Lines: For stamping, lifting, and repetitive operations requiring high precision . 👉· Robotics and Pick-and-Place: Grippers and manipulator arms where smooth .
