Bore (Cylinder Diameter): 254 mm Stroke (Extension Length): 975 mm

Parker Hydraulic Cylinder

1. General Description

The Parker hydraulic cylinder is designed for industrial applications requiring high force and reliable operation. With a bore of 254mm and a stroke of 975mm, it is a robust component, ideal for heavy machinery and applications requiring long stroke and high precision.

2. Materials and Construction

• Tubing : High strength steel, usually carbon steel or stainless steel. This material guarantees the ability to withstand high pressures and corrosion resistance.
• Stem : Stainless steel or heat-treated steel, designed to resist wear and corrosion.
• Seals : Made of resistant elastomers such as nitrile, Viton or polyurethane, capable of tolerating high pressures and temperature variations.
• Heads and Flanges : Cast or machined steel with surface treatments to ensure durability and stability.

3. Measurements and Dimensions

• Bore (Cylinder Diameter) : 254 mm
• Stroke (Extension Length) : 975 mm
• External Dimensions : They vary depending on the specific configuration of the cylinder and heads.

4. Mechanical Characteristics

• Maximum Working Pressure : 210 bar

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

  • FF $F$ is the force (Newton)
  • AA $A$ is the 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 254 mm bore : A=π×(0.2542)2≈0.0508 m2A = \pi \times \left(\frac{0.254}{2}\right)^2 \approx 0.0508 \, m^2 $A$ $=$ $\pi$ $\times$ $($ 2 0.254 ​) 2 $\approx$ $0.0508$ $m$ 2

  Force calculation: If a working pressure of 210 bar (21 MPa) is assumed: F=0.0508 m2×21000000 Pa=1,067,000 NF = 0.0508 \, m^2 \times 21000000 \, Pa = 1,067,000 \, N $F$ $=$ $0.0508$ $m$ 2 $\times$ $21000000$ $P$ $a$ $=$ $\mathrm{1,067,000}$ $N$ $($ $approximately$ $\mathrm{1,067}$ $kN$ )

• Extension/Retraction Speed : Depends on the fluid flow rate and the cylinder configuration.

5. Sectors of Use

• Manufacturing Industry : Used in machine tools, presses and assembly equipment.
• Construction sector : Suitable for heavy material handling and lifting applications.
• Energy Sector : Used in plants and machinery that require high strength and reliability.
• Heavy Industry : Used in lifting equipment and heavy machinery.

6. Advantages of Purchasing in Stock

• Immediate Availability : Reduces waiting times, improving operational efficiency and allowing a rapid start of operations.
• 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

Parker Hannifin Corporation is a global leader in fluid control solutions and motion technologies. Founded in 1917, Parker is known for its industrial innovation and quality. The company offers a wide range of hydraulic, pneumatic and control products for different applications, with a strong commitment to the reliability and durability of its solutions.

8. Calculation of Power at Different Pressures

The power required for the cylinder to operate can be estimated using 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=1,067,000 N×0.1 m/s=106,700 WP = 1,067,000 \, N \times 0.1 \, m/s = 106,700 \, W $P$ $=$ $1$ $,$ $067$ $,$ $000$ $N$ $\times$ $0.1$ $m$ $/$ $s$ $=$ $\mathrm{106,700}$ $W$ $approximately$ $106.7$ kW)

Conclusion

The Parker hydraulic cylinder with 254 mm bore and 975 mm stroke is a robust and reliable component, ideal for industrial applications requiring high forces and precision. The high-quality construction and high specification make it suitable for demanding environments.
