hydraulic cylinder 250 x 165

General Description
The hydraulic cylinder with 250 mm bore and 165 mm stroke is a component designed for industrial applications where high pressure performance is required. Mainly made of C45 steel for the heads and C35 for the cylindrical body, it offers high resistance to deformation and wear. The chrome plating of the piston guarantees durability even in corrosive environments.

Materials and components

• Jacket: C35 steel, smoothed internally and burnished externally
• Stem: Chrome-plated C45 steel with f7 tolerance, stainless steel version possible on request
• Bushing: Bronze B14
• Seals: NBR (for standard temperatures) or Viton (up to 200°C)

Technical characteristics

• Operating pressure: Up to 300 bar
• Operating temperature: -30°C to +120°C (cloth rubber) or up to +200°C (Viton)
• Movement speed: 10-30 mm/s in standard conditions

Mathematical formulas for force calculation
The force (F) produced by the cylinder can be calculated using the formula: F=p×AF = p \times A $F$ $=$ $p$ $\times$ $A$ where:

• pp $p$ is the pressure in Pascals (Pa)
• AA $A$ is the area of ​​the piston, calculable with A=π×(d2)2A = \pi \times \left(\frac{d}{2}\right)^2 $A$ $=$ $\pi$ $\times$ $($ 2 d ​) 2

For a 250 mm bore: A=π×(2502)2≈49.087 mm2=0.0491 m2A = \pi \times \left(\frac{250}{2}\right)^2 \approx 49.087 \, mm^2 = 0.0491 \, m^2 $A$ $=$ $\pi$ $\times$ $($ 2 250 ​) 2 $\approx$ $49$ $,$ $087$ $m$ $m$ 2 $=$ $0.0491$ $m$ 2

For a pressure of 200 bar (20 MPa): F=20×106 Pa×0.0491 m2≈982,000 NF = 20 \times 10^6 \, Pa \times 0.0491 \, m^2 \approx 982,000 \, N $F$ $=$ $20$ $\times$ $1$ $0$ 6 $P$ $a$ $\times$ $0.0491$ $m$ 2 $\approx$ $982$ $,$ $000$ $N$
