The single-acting hydraulic cylinder has only one oil port, and the movement in one direction is realized by oil pressure, and the return depends on the external force such as dead weight or spring. Only one end of the two chambers of this oil cylinder has oil, and the other end is in contact with air. Single-acting cylinders include single-rod cylinders, double-piston rod cylinders, plunger-type cylinders, and telescopic cylinders. For example, plunger hydraulics are abbreviated as plunger cylinders, which rely on hydraulic pressure for rising and self-weight for falling (return stroke). They are mostly used in vertical lifting applications, and are better than hydraulic plunger cylinders. Single acting hydraulic cylinder for sale has the following descriptions:
1. According to the structural characteristics: piston type, plunger type and swing type
2. According to the mode of action: single action and double action
The single-acting hydraulic cylinder can only make the piston (or plunger) move in one direction, that is, the pressure only leads to one cavity of the hydraulic cylinder, and the movement in the opposite direction must rely on external force (such as spring release or self-weight, etc.) to achieve; double-acting The movement of the hydraulic cylinder in both directions is realized by the push of pressure oil.
3. According to the use pressure
The hydraulic cylinder is a very important component for hydraulic machinery, and it plays the role of an executive element in the entire hydraulic machinery. The hydraulic cylinder converts hydraulic energy into mechanical energy in the whole process. According to the  specification, hydraulic cylinders can be divided into the following specifications according to the working pressure.
Host type design pressure (Mpa)
Low pressure hydraulic cylinder 0~3.5MPa
Medium and low pressure hydraulic cylinder 0~7.0MPa
Medium pressure hydraulic cylinder 7.0~14.0MPa
High pressure hydraulic cylinder 14~21.0MPa
Ultra-high pressure hydraulic cylinder above 21MPa
