Hydraulic cylinder

A hydraulic cylinder also called a linear hydraulic motor is a mechanical actuator that is used to give a unidirectional force through a unidirectional stroke.

It has many applications, notably in construction equipment , manufacturing machinery, elevators, and civil engineering.

Hydraulic cylinders are actuation devices that use pressurized hydraulic fluid to produce linear motion and force. They are used in a variety of power transfer applications, and can be single or double action. A single action hydraulic cylinder is pressurized for motion in only one direction, whereas a double action hydraulic cylinder can move along the horizontal (x-axis) plane, the vertical (y-axis) plane, or along any other plane of motion.

Important operating specifications for hydraulic cylinders include the cylinder type, stroke, maximum operating pressure, bore diameter, and rod diameter. Stroke is the distance that the piston travels through the cylinder. Hydraulic cylinders can have a variety of stroke lengths, from fractions of an inch to many feet. The maximum operating pressure is the maximum working pressure the cylinder can sustain. The bore diameter refers to the diameter at the cylinder bore. The rod diameter refers to the diameter of the rod or piston used in the cylinder.
