Tie Rod Type Hydraulic Cylinder 280x220x1400 mm · 模型 309914
Big Tie Rod Type Hydraulic Cylinder: This construction uses four or more high-strength threaded steel rods to hold the front and rear end caps to the cylinder barrel. This design is standard for NFPA (National Fluid Power Association) industrial cylinders and is known for its durability and serviceability. Leading manufacturers like Bosch Rexroth and AVENTICS produce these cylinders with key features such as high-tensile steel tie rods with rolled threads, one-piece ductile iron bearings, and advanced wear-resistant sealing systems . Flat Foot Fixed Mount (Style "B"): The "Flat Foot" or "Foot Mount" (often designated as Style "B") consists of two mounting feet, one bolted to the front end cap and one to the rear end cap . · "Fixed" Meaning: This is a rigid mount. The cylinder is bolted down by its feet and does not pivot. The mounting plane is offset from the cylinder's centerline. · Critical Consideration: Unlike centerline mounts (like trunnions), foot mounts impose a bending moment on the cylinder barrel when the cylinder pushes or pulls. For a cylinder this large (280 mm bore), this bending stress is significant and must be accounted for in the machine design . 👉Dimensions (280x220x1400 mm): · 280 mm: The Bore Diameter. This is the internal diameter of the cylinder barrel. It is exceptionally large, even for heavy-duty NFPA standards which typically range from 1.5 inches up to 14 inches (approx. 355 mm) . · 220 mm: The Rod Diameter. The thickness of the piston rod. The rod-to-bore ratio here is approximately 78% . This is a very robust ratio, providing exceptional column strength to prevent buckling under the massive compressive loads this cylinder will generate. · 1400 mm: The Stroke Length. The maximum distance the piston travels (1.4 meters). 👉2. Technical Characteristics Force Generation (Massive Capacity): This cylinder is rated for high-pressure operation, typically up to 210 bar (3,000 PSI) for NFPA industrial cylinders . · Example Calculation (at 210 bar / 3,000 PSI): · Piston Area = π × (14.0 cm)² ≈ 615.75 cm² · Push Force ≈ 615.75 cm² × 210 kg/cm² = 129,307 kg (approx. 129 Tons or 285,000 lbs). Rod Strength and Column Loading: The 220 mm rod diameter is crucial for stability. At full extension (1400 mm stroke), the rod acts as a long column. The heavy 78% ratio ensures a high safety factor against buckling under the 130-ton thrust force.
