CYLINDER Bore (Cylinder Diameter): 125 mm Stroke (Extension Length): 440 mm

Danieli Hydraulic Cylinder

1. General Description

The Danieli hydraulic cylinder with 125 mm bore and 440 mm stroke is designed for industrial applications requiring significant thrust force and significant extension length. This cylinder is ideal for machines and equipment that operate in heavy environments and require controlled force and long stroke.

2. Materials and Construction

• Tubing : Made of high-strength steel, typically carbon steel or stainless steel, to ensure high resistance to pressure and corrosion.
• Stem : Stainless steel or treated steel, designed to resist wear and corrosion, with a hardened finish to improve surface hardness.
• Seals : Elastomers such as nitrile (NBR), Viton or polyurethane, selected for their ability to withstand high pressures and temperature variations.
• Heads and Flanges : Machined or cast steel with surface treatments to increase strength and stability.

3. Measurements and Dimensions

• Bore (Cylinder Diameter) : 125 mm
• Stroke (Extension Length) : 440 mm
• External Dimensions : Varies based on the design of the cylinder and the configuration of the heads and flanges.

4. Mechanical Characteristics

• Working Pressure : Typically varies from 100 bar to 250 bar for cylinders of this size. The exact maximum pressure depends on the manufacturer's specifications and safety regulations.

• Thrust Force : F=A×PF = A \times P $F$ $=$ $A$ $\times$ $P$ Where:

  • FF $F$ is the force (Newton)
  • AA $A$ is the cross-sectional area of ​​the cylinder (m²)
  • PP $P$ is the pressure (Pa)

  Area calculation: A=π×(D2)2A = \pi \times \left(\frac{D}{2}\right)^2 $A$ $=$ $\pi$ $\times$ $($ 2 D ​) 2 For a 125 mm bore : A=π×(0.1252)2≈0.0123 m2A = \pi \times \left(\frac{0.125}{2}\right)^2 \approx 0.0123 \, m^2 $A$ $=$ $\pi$ $\times$ $($ 2 0.125 ​) 2 $\approx$ $0.0123$ $m$ 2

  Force calculation: If a working pressure of 200 bar (20 MPa) is assumed: F=0.0123 m2×20000000 Pa=246,000 NF = 0.0123 \, m^2 \times 20000000 \, Pa = 246,000 \, N $F$ $=$ $0.0123$ $m$ 2 $\times$ $20000000$ $P$ $a$ $=$ $\mathrm{246,000}$ $N$ (approximately 246 $kN$ $)$

• Extension/Retraction Speed : Depends on the fluid flow rate and the specific design of the cylinder.

5. Sectors of Use

• Manufacturing Industry : Used in machine tools, presses, and assembly equipment.
• Automotive sector : Suitable for testing and handling applications in workshops and production lines.
• Energy Industry : Used in plants and machinery requiring significant force and precise control.
• Heavy Industry : Used in machinery and equipment for lifting and moving heavy loads.

6. Advantages of Purchasing in Stock

• Immediate Availability : Reduces downtime, improving operational efficiency and reducing downtime.
• Competitive Prices : Purchasing from stock can lead to more favorable costs than special orders.
• Lower Risk of Interruptions : Ensures operational continuity by avoiding delays due to lack of components.

7. Brand and Manufacturer

8. Calculation of Power at Different Pressures

The power necessary for the operation of the cylinder can be estimated with the formula: P=F×vP = F \times v $P$ $=$ $F$ $\times$ $v$ where:

• PP $P$ is the power (Watts)
• FF $F$ is the force (Newton)
• vv $v$ is the cylinder speed (m/s)

Assuming an extension velocity of 0.1 m/s: P=246,000 N×0.1 m/s=24,600 WP = 246,000 \, N \times 0.1 \, m/s = 24,600 \ $,$ $W$ $P$ $=$ $\mathrm{246,000}$ $N$ $\times$ $0.1$ $m$ $/$ $s$ $=$ $\mathrm{24,600}$ $W$ $($ approximately 24.6 kW $)$
