Hydraulic Cylinders – Piston Ø 80 mm

The gold standard in agriculture and light industry. Hydraulic cylinders with an 80 mm piston diameter are the most popular choice for front loaders (TUR), agricultural machinery, and high-speed log splitters. They generate a pressing force of 8–10 tons , providing the perfect balance between power and extension speed. Robust construction, chrome-plated piston rods, and full remanufacturing.

Hydraulic cylinders Ø 80 mm - Versatile Power

This category includes double-acting hydraulic cylinders with an 80 mm internal diameter piston. This is the most versatile size on the market, constituting the "heart" of most medium- and high-power agricultural machinery and many municipal equipment.

Why is Ø 80 mm such a popular choice?

The "80" cylinder offers an optimal ratio of force to oil consumption. Unlike larger cylinders (e.g., Ø 100 mm), it doesn't require a high-capacity pump to operate quickly, yet it's significantly more powerful than standard Ø 63 mm cylinders.

Force parameters (Piston surface ~50 cm²):

  • At a pressure of 160 bar (agricultural standard): Extension force approx. 8 tons .
  • At a pressure of 200 bar : Extension force approx. 10 tons .
  • At a pressure of 250 bar : Extension force approx. 12.5 tons .

Main applications

Thanks to their characteristics, these actuators drive:

  1. Front loaders (TUR): As the main frame lifting cylinders in tractors such as Ursus C-360, Zetor, MF and newer designs (loader lifting capacity approx. 1200-1600 kg).
  2. Fast log splitters: Ideal for home and semi-professional construction (10-12 tons of pressure), where we want a faster work cycle than in slow Ø 100 mm cylinders.
  3. Agricultural machinery: Heavy disc harrows, reversible ploughs, round balers, seed drills.
  4. Sweepers and snow plows: To control the blade angle.

Construction and Quality

The Ø 80 mm cylinders we offer are products adapted to work in difficult conditions (dust, mud, variable temperatures):

  • Piston rod: Most often with a diameter of Ø 40 mm, Ø 45 mm or Ø 50 mm . The surface is hardened and covered with a layer of technical chrome to protect against corrosion.
  • Cylinder: Tube honed to H8 tolerance, ensuring internal tightness.
  • Mounts: Available variants with swivel bearings (so-called apples), weldable sleeves or threads, which facilitates adaptation to any frame.

FAQ: Hydraulic Cylinders – Piston Ø 80 mm – Questions and Answers
1. What is the pressing force (lifting capacity) achieved by an actuator with a piston diameter of 80 mm?

80mm cylinders generate powerful forces, ideal for heavy-duty applications. The piston's effective area is approximately 50.2 cm². Depending on system pressure:

  • At a pressure of 160 bar (common in older agricultural hydraulics), the cylinder pushes the weight with a force of approximately 8.2 tonnes (8,200 kg).
  • At a standard operating pressure of 200 bar , the pressing force exceeds 10 tons (approx. 10,240 kg).
  • In modern systems operating at a pressure of 250 bar , an 80 mm cylinder can generate a pressure of almost 12.8 tons .
2. What machines are most often built with an 80 mm cylinder?

Its 10-ton force makes it a component for special tasks. Common applications include:

  • Heavy log splitters: This is the absolute standard in the construction of professional hydraulic log splitters (horizontal and vertical) with a working pressure of 10-12 tons, capable of handling the most knotty oak or beech wood.
  • Hydraulic presses: The actuator in workshop and industrial presses.
  • Heavy agricultural and construction equipment: Main lift cylinders on large front loaders, tipping cylinders on heavy agricultural trailers (dump trucks) and excavator arms.
3. Why is the thickness of the piston rod (rod) so important in 80 mm cylinders?

At pressures of around 10 tons, the rod extending from the cylinder is subjected to extreme axial stresses. 80 mm cylinders use thick piston rods – typically 40 mm to even 50 mm .
If you're building a long-stroke machine (e.g., a log splitter with a 500-1000 mm stroke), you'll need to choose the variant with the thickest bar (e.g., 50 mm). Pushing 10 tons at maximum extension with a thin bar would almost certainly result in permanent bending of the bar (known as buckling).
4. What pump and distributor does an 80mm piston cylinder require?

The large diameter of the piston means that the cylinder has a large capacity (requiring a huge amount of oil to be pumped).

  • Using a weak pump (e.g. 20 l/min) will cause the 80 mm cylinder to extend very slowly.
  • For smooth and fast operation, we recommend using a pump with a capacity of at least 40 to 80 l/min and a sufficiently large distributor (e.g. flow rate 80 l/min or a CETOP 05 size valve) to avoid choking the system.
5. How to install a hydraulic cylinder generating a force of 10 tons?

With such forces, standard "push-and-pull" mountings are out of the question. BRhydraulic's 80mm cylinders are typically equipped with robust eyelets with pressed-in swivel bearings (e.g., for a Ø 35mm or Ø 40mm pin). The swivel bearing is crucial because it minimally compensates for unevenness and stresses in the machine frame during operation, preventing the mounting eyelet from breaking.
