Introduction: Why Hydraulic Cylinders Matter in Modern Industry

Hydraulic cylinders are the driving force behind Europe’s most demanding industrial applications—from heavy construction and steel production to marine, renewable energy, and advanced manufacturing. As linear actuators, they convert hydraulic energy into controlled mechanical motion, delivering unmatched power density, precision, and reliability.

At Hidroman, we approach hydraulic cylinders not merely as components, but as engineered solutions. Our philosophy is built on trust, durability, and premium quality, aligning with European expectations for safety, performance, and long-term value.

This guide is designed to be an authoritative reference for hydraulic cylinders in Europe—covering fundamentals, standards, design criteria, and best practices.

What Is a Hydraulic Cylinder?

A hydraulic cylinder is a mechanical actuator that uses pressurized hydraulic fluid to generate linear force and motion. It typically consists of:

Cylinder Barrel – Houses the pressure chamber

Piston & Piston Rod – Transmit force and motion

Seals & Bearings – Ensure pressure retention and smooth movement

End Caps / Heads – Close the barrel and guide the rod

By applying Pascal’s Law, hydraulic cylinders deliver consistent force even under extreme loads, making them indispensable in heavy-duty systems.

Types of Hydraulic Cylinders (European Industry Standard)

1. Single-Acting Hydraulic Cylinders

Single-acting cylinders apply force in one direction, with return motion achieved by gravity, spring, or external load.

Typical Applications: - Lifting platforms - Agricultural machinery - Simple pressing operations

Advantages: - Simple design - Lower cost - Reduced maintenance

2. Double-Acting Hydraulic Cylinders

Double-acting cylinders apply hydraulic pressure in both extension and retraction strokes.

Typical Applications: - Construction equipment - Industrial automation - Steel and metal processing lines

Advantages: - Full motion control - Higher precision - Superior productivity

3. Telescopic Hydraulic Cylinders

Designed with multiple nested stages, telescopic cylinders provide long stroke lengths in compact installations.

Typical Applications: - Tipper trucks - Mobile cranes - Waste management vehicles

4. Tie-Rod Hydraulic Cylinders

Commonly used in industrial environments, tie-rod cylinders are compliant with ISO standards and easy to service.

Standards: ISO 6020 / ISO 6022

5. Welded Body Hydraulic Cylinders

Welded cylinders offer a compact and robust design, ideal for mobile and heavy-duty applications.

Key Benefits: - High pressure resistance - Compact installation - Excellent fatigue strengt

ISO & European Standards for Hydraulic Cylinders

Compliance with European and international standards is critical for safety, interchangeability, and system reliability.

Key standards include:

ISO 6020 / 6022 – Tie-rod and heavy-duty cylinders

ISO 3320 – Cylinder dimensions and mounting

EN 13445 – Pressure vessel safety principles

DIN Standards – Widely used across Germany and Central Europe

At Hidroman, all hydraulic cylinders are engineered to meet or exceed relevant ISO and EN standards, ensuring seamless integration into European hydraulic systems.

Key Design Parameters of Hydraulic Cylinders

When selecting or designing a hydraulic cylinder, the following parameters are critical:

Bore Diameter – Determines force output

Rod Diameter – Affects buckling resistance

Stroke Length – Defines motion range

Operating Pressure – Commonly 160–350 bar in Europe

Mounting Type – Clevis, flange, trunnion, foot

Seal Technology – Vital for efficiency and service life

Premium cylinder performance depends on the correct balance of all these factors.

Hydraulic Cylinder Applications Across Europe

Hydraulic cylinders are widely used in:

Construction & Infrastructure

Mining & Quarrying
