Hydraulic cylinders essentially convert fluid pressure and flow into force and linear motion. They are available in a wide range of styles, sizes, materials, and configurations. Many OEM engineers play it safe by over-engineering cylinder specifications. But less can sometimes be more when it comes to complex hydraulics.
Hydraulic cylinders haven't really changed a lot over the years. The manufacturing processes are much more streamlined and the tolerances are much tighter, but for the most part cylinders are still the hard working push/pull tools they have always been. These things have literally shaped the world around us.
Anything that gets lifted, pushed, hauled, dumped, dug, crushed, drilled or graded has gotten that way by some truck, crane, dozer or tractor using a hydraulic cylinder.
The amazing amount of force a cylinder exerts is due to the simple mechanical principle of pressure exerted on the surface area of the piston. Simply put, the larger the diameter of the cylinder, the more it will lift.
