Wondering which hydraulic cylinder will be suitable for your log splitter, front loader, or workshop press? The key to success is choosing the right diameter. In this article, we will guide you through the most popular sizes of hydraulic cylinders available at BRhydraulic.eu and advise which one will provide you with adequate power.
A hydraulic cylinder is the muscle of your machine. It converts oil pressure into a specific force that lifts, moves, or crushes. Our customers often face a dilemma: "Will an 80 mm cylinder be enough, or do I need to buy a hundred?".
The answer depends on two factors: the pressure in your system and the piston surface area. The larger the diameter, the greater the force, but (with the same pump) the slower the movement.
Piston or Piston Rod? Don't confuse these dimensions!
Before we dive into the overview, let's clarify the most common purchasing mistake.
-
Piston Diameter (Cylinder): This is the internal dimension of the tube. This parameter determines the FORCE of the cylinder. Commercially, when we say "80-series cylinder," we are referring to the piston diameter.
-
Piston Rod Diameter (Rod): This is the chrome-plated rod that extends from the housing. Its thickness determines its RESISTANCE to bending.
In the following overview, we discuss the piston (cylinder) diameters.
1. Ø 50 mm Cylinders – Speed and Precision
Small but mighty. This is the smallest standard dimension in power hydraulics.
-
Force (at 200 bar): approx. 3.9 tons
-
Application: Power steering systems (C-330, T-25), control of seeder markers, opening flaps, small orchard lifts.
-
For whom? For those who need very fast operation with low oil demand. Ideal for auxiliary functions where high crushing force is not required.

2. Ø 63 mm Cylinders – The Golden Mean for Light Work
A compact size that offers significantly greater force than the "fifty," while maintaining high operating dynamics.
-
Force (at 200 bar): approx. 6.2 tons
-
Application: Bale wrappers, grapples, power steering in heavier tractors (C-360, Zetor), industrial gate openers.
-
For whom? An ideal choice if you are building a light machine and have a pump with a capacity of 20-30 l/min.

3. Ø 80 mm Cylinders – The King of Agriculture (Bestseller)
This is by far the most popular size in Poland. If you see a front loader (TUR) in the field, it probably runs on cylinders of this diameter.
-
Force (at 200 bar): approx. 10 tons
-
Application: Main lifting cylinders in front loaders, fast log splitters (8-10 tons pressure), cultivators, snow plows.
-
For whom? For farmers and constructors. This is the best compromise between strength, speed, and price. A force of 10 tons is sufficient for splitting most logs while maintaining a fast operating cycle.

4. Ø 100 mm Cylinders – Heavyweight
We are entering the zone of high power. A "hundred" cylinder is a powerful tool that requires a solid machine frame.
-
Force (at 200 bar): approx. 15.7 tons
-
Application: Professional hydraulic log splitters (handling knotty oak), 15-20 ton workshop presses, construction machinery, heavy harrows and subsoilers.
-
For whom? If you are building a log splitter that needs to "go through anything," choose Ø 100 mm. Remember, however, that this cylinder has a large capacity – it requires an efficient pump (min. 40 l/min) for the work not to be too slow.

5. Ø 125 mm Cylinders – Industrial Giant
The largest standard cylinder in our offer. This design is for those who do not compromise.
-
Force (at 200 bar): approx. 24.5 tons (at 300 bar, even 37 tons!)
-
Application: Heavy industrial presses, scrap compactors, pellet production machines, large sawmill equipment.
-
For whom? Exclusively for industrial and specialized applications. Mounting such a cylinder requires the use of large-diameter pins and a very robust support structure.

Force Selection Table (Cheat Sheet for the Designer)
To make your choice easier, we have prepared a simple overview of theoretical forces (extension) for different pressures:
| Piston Diameter | Force at 160 bar (Standard C-330/C-360) | Force at 200 bar (Newer Tractors/Power Units) | Force at 250 bar (Max. industrial) |
| Ø 50 mm | 3.1 tons | 3.9 tons | 4.9 tons |
| Ø 63 mm | 5.0 tons | 6.2 tons | 7.8 tons |
| Ø 80 mm | 8.0 tons | 10.0 tons | 12.5 tons |
| Ø 100 mm | 12.5 tons | 15.7 tons | 19.6 tons |
| Ø 125 mm | 19.6 tons | 24.5 tons | 30.6 tons |
Note: The values given are theoretical. In practice, approximately 5-10% should be subtracted for seal friction resistance.
Summary
Choosing a cylinder is always a compromise.
-
Looking for versatility for a front loader? Choose Ø 80.
-
Need powerful crushing for a press or log splitter? Aim for Ø 100 or Ø 125.
