What are the differences between the oscillating cylinder and the ordinary cylinder?

Most of our friends don't have a thorough understanding of swing cylinders and ordinary cylinders. What are the differences between them? Let's take a look together! 

The air viscosity of ordinary cylinders is lower, resulting in less resistance compared to hydraulic oscillating cylinders. The control of air cylinders is convenient, they are relatively inexpensive, and energy is readily available. However, the force is small and it cannot achieve a stable speed effect. Oscillating cylinders have a small volume and a large force, they can operate at constant speed or variable speed, and the adjustment of output is relatively convenient. The freedom of transmission is also higher. From the perspective of the medium, air is inexhaustible, there are no costs or supply difficulties, and the used gas can be directly discharged into the atmosphere, which is convenient to handle and will not cause pollution. Since the pressure used in pneumatic systems is generally in the range of 0.2 - 1.0 Mpa, air cylinders cannot be used as power components with large power. Hydraulic oscillating cylinders can be used as components with relatively large power, and the oil cylinder system can be used. 

The special feature of the structure is that in order to achieve reliable functionality, high manufacturing precision is required. Due to the small size of the oscillating cylinder, the strength and reliability cannot be perceived. The powerful HKS oscillating cylinder can rotate 20 Volkswagen Golf sedans from one side to the other. This design is based on a system with multiple spiral gears. The multiple spiral gears convert the linear motion of the piston into rotational motion. The longer the linear motion of the piston, the greater the rotational angle.
