Hydraulic cylinders are among the most important components of power hydraulic systems. They convert the energy of pressurized oil into linear motion – lifting, pushing, pulling, or pressing. At BRhydraulic.eu, you'll find a wide selection of cylinders for agricultural, construction, municipal, and industrial machinery. This article will help you understand how cylinders work, their different types, and how to choose the right model for your machine.
What is a hydraulic cylinder ?
A hydraulic cylinder is an actuator that converts oil pressure into mechanical force. Inside, it houses a piston that moves along a cylinder under the influence of oil pressure. This allows cylinders to generate enormous forces in a relatively small size.
The most important advantages of hydraulic cylinders :
- high potency,
- smooth and precise operation,
- resistance to overloads,
- ability to work in difficult conditions,
- long service life with proper operation.
Types of hydraulic cylinders
BRhydraulic.eu offers various types of cylinders to suit many applications.
1. Single-acting cylinders
They operate in one direction only – the return is achieved by a spring or the weight of the working element. They are used in applications such as:
- lifts,
- dump trucks,
- simple agricultural systems.
2. Double-acting cylinders
The most common type. Oil acts on the piston in both directions, providing complete control over movement.
Perfect for:
- loaders,
- construction machinery,
- hydraulic presses,
- industrial machines.
3. Telescopic cylinders
They consist of several extendable sections, which allows for a very large stroke with compact dimensions.
Used in:
- dump trucks,
- lifts,
- municipal vehicles.
How to choose a hydraulic cylinder ?
Choosing the right actuator depends on several key parameters.
1. Piston and rod diameter
The larger the diameter, the greater the force generated by the actuator.
2. Actuator stroke
Determines the maximum range of motion. It must be adapted to the machine's design.
3. Working pressure
Most often 160–250 bar in agricultural machines and 300+ bar in industrial machines.
4. Mounting method
Most popular:
- ear-ear,
- ear-fork,
- ball joint,
- non-standard mountings.
5. Type of machine operation
One type of actuator will work well in a baler, another in a loader, and yet another in a dump truck.
The most common applications of hydraulic cylinders
Actuators are used in:
- agricultural machinery (ploughs, loaders, balers, spreaders),
- construction machines (excavators, loaders, lifts),
- industrial hydraulics (production lines, presses, manipulators),
- municipal and specialized vehicles,
- transport and lifting systems.
Why is it worth buying cylinders at BRhydraulic.eu ?
The store offers:
- a wide selection of actuators for various applications,
- products from proven manufacturers,
- full technical specifications,
- the ability to adapt the actuator to a specific machine,
- fast shipping and professional advice,
- attractive prices and constant availability of spare parts.
It is an ideal place for farmers, mechanics, service companies and individual users.
How to extend the life of the actuator?
A few simple rules:
- regular oil and filter changes,
- checking the tightness of the system,
- avoiding overload,
- using pipes with appropriate pressure,
- protection of the piston rod against dirt.
Thanks to this, the actuator will work longer and without failure.
Hydraulic cylinders are the foundation of many machines and devices. Their correct selection impacts the efficiency, safety, and durability of the entire system. At BRhydraulic.eu, you'll find single-acting, double-acting, and telescopic cylinders, as well as a full range of accessories, allowing you to create a reliable hydraulic system.
