Rely on tested quality and order pistons, cylinder bores and associated components online.

Central unit

The piston and cylinder are the heart of the engine: The piston converts the pressure of combustion into movement and transfers this to the connecting rod and crankshaft. At the same time, it seals the combustion chamber and dissipates heat – it also regulates oil consumption and sealing via piston rings.

Strength in the body

For optimum performance, the piston, cylinder bore and rings must be precisely matched. The tolerances are crucial – too tight and it rubs, too wide and compression escapes. The materials and surface treatment influence wear, thermal conductivity and service life.

Multi-stage tipping cylinder for trucks

High-performance cylinders and pistons for demanding commercial vehicles
In the world of heavy-duty transportation, the reliability of lifting and pressure systems is crucial. A precisely manufactured cylinder, together with a robust piston, forms the heart of powerful hydraulic and pneumatic systems. Whether as a tipping cylinder for bulk goods transportation or as a control element in complex vehicle assemblies – the quality of the cylinder running surfaces and the accuracy of fit of the piston rings determine the efficiency of the power transmission. At FZB Fahrzeugbedarf, we rely on components that have been specially developed for the extreme pressures and load cycles in commercial use in order to minimize downtimes.

Durability through first-class cylinder technology and material selection
Wear on cylinders and pistons often manifests itself gradually through pressure loss or leaks. To maximize the service life of your system, it is essential to choose the right materials – from hardened piston rods to highly resistant seal sets. A high-quality cylinder must not only withstand mechanical loads, but also be protected against external influences such as dirt and corrosion. Our spare parts in OEM quality guarantee a precise modular design that enables fast repairs and ensures the long-term operational safety of your truck.

What should you look out for when buying:

MOTORTYP

Make sure that the piston or bore matches the engine variant – dimensions, stroke and design details must be correct.

COATING

Choose pistons and raceways with high-quality coatings or surface finishes that minimize friction and reduce wear.

RINGS

Check which ring grooves are present and which ring set belongs to them – sealing and oil wiping depend largely on this.

Expert FAQ: Everything about cylinders, pistons and hydraulic lifting systems

The cylinder converts the energy of a fluid (hydraulic oil or compressed air) into a linear movement in order to lift or press heavy loads or to control components.

Typical signs are a decrease in lifting force, scoring on the piston rod, hydraulic oil leakage or uneven movement sequences.

Single-acting cylinders only work with pressure in one direction (retraction often due to gravity), while double-acting cylinders can actively exert force in both directions.

The piston rod must be extremely smooth (usually hard chrome-plated) so that the seals are not damaged and the system remains absolutely tight even under high pressure.

Yes, a professional repair kit with new gaskets and wipers is often sufficient, provided the cylinder running surface and the piston do not show any deep mechanical damage.

Impurities in the oil act like sandpaper between the piston and cylinder wall, leading to rapid wear and internal leaks.

Tipping cylinders are usually multi-stage telescopic cylinders that enable large strokes to be achieved in a compact design in order to raise the loading area of tippers.

The exact diameter, material compatibility with the existing seals and suitability for the specific operating pressure of the system are important.
