Specifications:
Hydraulic cylinders are an important industrial tool used in machinery, manufacturing, and a number of other functions. The basic design of a hydraulic cylinder has changed little over the years. Hydraulic cylinders have enormous push/pull power and can haul, dig, push, drill, and move heavy objects and materials. The work by exploiting the mechanics of pressure exerted on the piston. The force is equal to the surface area multiplied by pounds per square inch of pressure.
