A hydraulic cylinder is a mechanical device for transporting power by using large pressure oil acting on the facade area of the piston in the cylinder. A hydraulic cylinder provides linear force in one axis in one or both directions (known as single or double-acting cylinder respectively). You can browse through the internet to get good quality hydraulic cylinders online. Cylinder usually consists of four or five components:
- Piston (optional)
In a typical hydraulic cylinder with a piston oil included in at both ends through some kind of 'port' and piston sealed into a tube with double-acting seal and also between the rod and the gland with a single-acting seal. Additionally, you will typically find use in the gland wiper seal to keep dirt out. This illustration is known as a double-acting cylinder.

It is the pressure acting on the piston surface which causes the hydraulic cylinder to generate a linear movement. Because the rod is fixed to the piston, moving well. The application of hydraulic pressure through a port to one side of the piston causing it to move in one direction, and the application of pressure through the port to the opposite side of the piston will cause it to move in the opposite direction.
In a single-acting cylinder, oil only works on one side of the piston that can only be mechanically moved in one direction. External forces (gravity, or sometimes springs or other hydraulic cylinders) provide power in the opposite direction.
