Hydraulic cylinder is a hydraulic executive component that can translate the hydraulic energy to mechanical energy and can do straight reciprocating motion. It has a simple structure and can working relable. It is wildly used in hydraulic system machinery because of the un-reduction gear and no transmission gap when doing reciprocating motion. Hydraulic cylinder output force, piston effective area and their differential pressure is changed as direct ration. It is made up of cylinder body and head, piston and piston rod, sealing, shocks and exhaust devices. The shocks and exhaust devices is used based on the situation, but the other devices are be must.
