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 254 mm bore and 975 mm stroke, it is a robust component, ideal for heavy machinery and applications requiring long strokes and high precision.

2. Materials and Construction

• Pipe : High-strength steel, usually carbon steel or stainless steel. This material provides high-pressure capability and corrosion resistance.
• Stem : Stainless steel or heat-treated steel, designed to resist wear and corrosion.
• Seals : Made of durable elastomers such as nitrile, Viton or polyurethane, capable of tolerating high pressures and temperature variations.
• Headers 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 : Varies depending on the specific cylinder and head configuration.

4. Mechanical Characteristics

• Maximum Working Pressure : 210 bar

• Pushing 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 $a$ $=$ $\mathrm{1,067,000}$ $N$ $($ $about$ $1.067$ kN $)$

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

5. Sectors of Use

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

6. Advantages of Stock Purchase

• Immediate Availability : Reduces downtime, improving operational efficiency and enabling rapid start-up of operations.
• Competitive Pricing : Buying from stock can result in more favorable costs than special orders.
• Lower Risk of Outages : Ensures operational continuity by avoiding delays due to component shortages.

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 innovation and quality in the industrial sector. The company offers a wide range of hydraulic, pneumatic, and control products for a variety of applications, with a strong commitment to the reliability and durability of its solutions.

8. Calculating Power at Different Pressures

The power required to operate the cylinder can be estimated using the formula: P=F×vP = F \times v $P$ $=$ $F$ $\times$ $v$ where:

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

Assuming an extension velocity of 0.1 m/s: $m$ /s=106,700 WP = 1,067,000 \, N \times 0.1 \, m/s = 106,700 $\backslash$ $,$ $W$ $P$ $=$ $\mathrm{1,067,000}$ $N$ $\times$ $0.1$ $m$ $/$ $s$ $=$ $106$ $,$ $700$ $W$ (approximately 106.7 kW)

Conclusion

The Parker hydraulic cylinder with a 254 mm bore and 975 mm stroke is a robust and reliable component, ideal for industrial applications requiring high forces and precision. Its high-quality construction and high specifications make it suitable for demanding environments. Buying it immediately from stock offers significant advantages in terms of availability and cost, improving operational efficiency and reducing downtime.
