HYDRAULIC CYLINDERS
Hydraulic cylinders convert hydraulic energy into linear force and consequently movement. They operate based on Pascal's law principle and utilize the force generated by the pressure of a closed fluid - oil. When hydraulic fluid is pumped to one side of the cylinder, it pushes the piston, creating linear movement in the desired direction.
Common double-acting hydraulic cylinders ('differential cylinders') have two ports (for hydraulic hoses), allowing linear movement in both directions.

Due to the different surface area ratios of the pressed oil on one side or the other of the cylinder, the cylinder also has different power when extending or retracting. Consequently, due to the different oil volumes on one side or the other of the cylinder, the speed of the cylinder (piston) is also different (faster or slower). When 'extending' the cylinder, the oil acts on the entire surface of the piston, which is why the cylinder performs greater force in this case and moves slower, whereas during 'retracting', where the surface is smaller by the diameter of the piston rod, the cylinder overcomes less force, allowing it to move faster.
Applications of hydraulic cylinders:
Hydraulic cylinders are useful wherever there is a need for greater power. In agriculture, hydraulic cylinders are used for tractors (lifting arms of three-point linkages, top links, hydraulic steering, loaders, front linkage, etc.), combines, loaders, etc. They are equally widely used on various tractor attachments, such as spider, loader, tipper trailer, log splitter, flap on slurry tanks, harrows, movement of tillers and mulchers, silage grabbers, turning plows for soil, snow plows, forestry winches, etc.
Hydraulic cylinders are also very commonly used in forestry, machinery construction, construction, shipbuilding, energy, food industry, automotive industry.
We know several types of hydraulic cylinders (different mountings):
Hydraulic cylinders are available in various dimensions and with diverse mountings to meet different needs.
