The 90x400 hydraulic cylinder is a hydraulic component designed for applications where linear movement with high force is required. Its robustness, combined with high performance and versatility, makes it ideal for heavy industrial uses. In this technical sheet, we will explore in detail all the characteristics of the cylinder, from its construction to its most common uses, offering precise information for those who wish to purchase a quality hydraulic cylinder.

1. Main Technical Data of the 90x400 Hydraulic Cylinder

• Bore (piston diameter) : 90 mm (9 cm)
• Travel (stroke) : 400 mm
• Connecting rod diameter : 45 mm (approximately, depending on model)
• Nominal pressure : 180 bar (typical for medium power industrial applications)
• Test pressure : 270 bar
• Fluid flow rate : From 30 l/min to 90 l/min , based on the speed of movement and the specifications required.
• Operating temperature : -20°C to +80°C (suitable for a wide range of industrial applications and working environments)
• Materials:
  • Cylinder body : Made of carbon steel or stainless steel , to withstand high pressures and ensure long life.
  • Piston : Hardened steel with surface treatment for wear resistance.
  • Seals : NBR (Nitrile) or Viton , materials suitable for use in working environments with variable temperatures and pressures.
  • Connecting rod : In tempered steel with protective finish against wear and corrosion.

2. Mechanical Characteristics and Operation

The 90x400 hydraulic cylinder is designed to work under high pressure and generate considerable force. Its operation is based on the principle of converting hydraulic energy into mechanical movement.

Composition and Operation:

• Cylinder body : The main part that houses the hydraulic fluid, ensuring resistance to high pressures and mechanical shocks.
• Piston : The moving part that moves under fluid pressure, transforming hydraulic energy into linear motion.
• Connecting rod : Transmits the movement of the piston to the mechanical part to be moved.
• Seals : They guarantee the tightness of the cylinder and prevent fluid leaks, ensuring optimal efficiency over time.

When the fluid enters the cylinder, it exerts pressure on the piston which, in turn, generates linear movement. The efficiency of a cylinder depends on the quality of the materials, correct lubrication and periodic maintenance.

3. Force Calculation

The force generated by the cylinder depends on the pressure and the cross-sectional area of ​​the piston.

Formula for calculating force:

The formula to determine the force generated by the cylinder is:

$$F$$

Where:

• F is the force (in Newtons, N)
• P is pressure (in Pascal, Pa)
• A is the cross-sectional area of ​​the piston (in m²)

The area of ​​the piston is calculated using the formula for the area of ​​a circle:

$$A$$

Where D is the diameter of the piston, in this case 90 mm (0.09 m):

$$0.0254$$

Force calculation:

If the nominal pressure is 180 bar (i.e. 18,000,000 Pa ), we can calculate the force:

$$F$$

Thus, the cylinder exerts a force of 457,200 Newtons at a nominal pressure of 180 bar .
