Hydraulic Cylinder 370x190

General Description

A hydraulic cylinder with a bore of 190 mm and a stroke of 370 mm is a component used to convert fluid energy into linear motion. This type of cylinder is often used in applications where great force is required, such as industrial machinery, material handling equipment, and construction equipment.

Construction Materials

• Cylinder : Generally made of carbon steel or high strength alloy steel. The cylinder body is usually seamless tubing, heat treated to withstand high pressures.
• Piston : Hardened and chromed steel to resist wear and ensure long life.
• Stem : Chrome steel or stainless steel with surface treatments to reduce friction and protect against corrosion.
• Seals : In Viton, NBR or polyurethane, to guarantee tightness and prevent oil leaks.

Dimensions and Measurements

• Bore : 190 mm
• Stroke : 370 mm
• Stem diameter : Typically smaller than bore, dependent on specific application (e.g. 90-100 mm).
• Maximum working pressure : Normally between 160 and 250 bar, but may vary depending on the project.

Mechanical Characteristics

• Thrust force : Depends on the fluid pressure applied to the piston area. The formula for calculating force is:

  $$F$$

  Where:

  • FF $F$ = Force in Newton (N)
  • PP $P$ = Pressure in Pascals (Pa)
  • AA $A$ = Piston area, calculated as π×r2\pi \times r^2 $\pi$ $\times$ $r$ 2

  In the case of our 190 mm bore :

  If the working pressure is 200 bar ( 200×105 Pa200 \times 10^5 \, Pa $200$ $\times$ $1$ $0$ 5 $P$ $a$ ):

  $$F$$

• Retraction force : Less than the pushing force, since the area on which the pressure acts is reduced by the surface of the rod.

Use in Industrial Sectors

1. Construction machinery : Excavators, cranes, bulldozers.
2. Manufacturing industry : Hydraulic presses, automated assembly lines.
3. Agricultural sector : Equipment for tractors and harvesters.
4. Maritime and naval sector : Control of heavy mechanical systems such as doors and winches.

Advantages of Prompt Delivery Purchase (Stock)

1. Reduction of downtime : The immediate availability of a cylinder allows you to reduce the downtime of the machines.
2. Greater economic convenience : Stock cylinders are often offered at competitive prices, as they are produced in large volumes.
3. Quality assurance : Cylinders available in stock have often already passed standardized quality checks, ensuring reliability.

Builder

Often brands like Parker Hannifin , Bosch Rexroth , or Hydac are known for producing high quality hydraulic cylinders. These manufacturers also provide certifications of compliance with ISO standards, guaranteeing robustness, precision and durability over time.

Power at Various Pressures

To hypothesize the power at different pressures, we can use the following formula:

$$P$$

Where:

• PP $P$ is the power,
• FF $F$ is strength,
• vv $v$ is the rod speed.

If we assume operating pressures varying between 160 and 250 bar, we can calculate the force produced and therefore estimate the power delivered by the cylinder based on the speed of extension or retraction.

This cylinder, with its large bore and stroke, is ideal for heavy-duty applications and where great thrust force and precision is required. Purchasing ready for delivery guarantees immediate availability, reducing the risk of production downtime.
