Hydraulic Cylinder Piston

A Hydraulic Cylinder Piston is a component inside a hydraulic cylinder. It divides the cylinder into two chambers. The piston is allowed to slide inside the cylinder, but seals against the inside of the cylinder with a rubber o-ring or seal. A increase in fluid pressure on either side of the piston will cause the piston to move up (or down) in the cylinder; in this manner, a change in pressure is converted to linear motion. A piston rod is attached to one end of the piston and exits the cylinder through a sealed rod gland.
