The hydraulic cylinder stroke is the difference between the maximum total length when the hydraulic cylinder is ejected and the minimum total length when it is stowed.

The stroke of the oil cylinder should be the stroke of the hydraulic cylinder, which refers to the action length of the piston rod. The hydraulic cylinder with buffer device includes the buffer length.

Hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has simple structure and stable operation. When it is used to realize reciprocating motion, it can avoid the reduction device, and there is no transmission gap, so it is widely used in the mechanical hydraulic system. The output force of the hydraulic cylinder is directly proportional to the piston area and the pressure difference on both sides; The hydraulic cylinder is basically composed of cylinder barrel and cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. The buffer device and exhaust device depend on the specific application, and other devices are indispensable.
