Hydraulic cylinders and pneumatic cylinders are devices that change fluid pressure energy into mechanical energy.

Hydraulic cylinders and pneumatic cylinders are devices that change fluid pressure energy into mechanical energy. They are also known as actuators, and have been widely used in various control devices. In the form of movement, actuator includes hydraulic cylinders or pneumatic cylinders for straight motion, motors for turning motion, pendulum actuators for rotational motion and other types of actuators. The pneumatic cylinder uses compressed air as the source of gas and converts the pressure energy of the gas into mechanical energy.
Choices for cylinder type include tie-rod, welded, and ram. A tie-rod cylinder is a hydraulic cylinder that uses one or more tie-rods to provide additional stability. Tie-rods are typically installed on the outside diameter of the cylinder housing. In many applications, the cylinder tie-rod bears the majority of the applied load. A welded cylinder is a smooth hydraulic cylinder that uses a heavy-duty welded cylinder housing to provide stability. A ram cylinder is a type of hydraulic cylinder that acts as a ram. A hydraulic ram is a device in which the cross-sectional area of the piston rod is more than one-half of the cross-sectional area of the moving components. Hydraulic rams are primarily used to push rather than pull, and are most commonly used in high-pressure applications.
1.
Single acting cylinder: Structurally, only one side of the piston provides fluid with a certain pressure. A single acting cylinder controls movement by a fluid force in one direction, and the return process depends on external forces such as spring force or gravity.

2.
Double acting cylinder: Structurally, both sides of the piston are supplied with the fluid of certain working pressure. Under the influence of fluid force of both sides, the hydraulic cylinder or pneumatic cylinder can move in the positive direction or the reverse direction.

Generally, when the asymmetry of a hydraulic cylinder or pneumatic cylinder is negligible, the initial position of the piston is in the neutral position of the cylinder, and the two sides can be regarded as a symmetrical structure.
