Cylinders

Cylinders, also known as pneumatic actuators or air cylinders, use gas to create force or motion. They function similarly to hydraulic cylinders, but instead of using fluids, they rely on compressed air as a power source.

These cylinders are often used in industries that require fast and efficient motion, such as automation, food processing, and packaging. Cylinders are lightweight, easy to install, and low maintenance, making them a popular choice for many industrial applications. Cylinders come in a variety of sizes and types to suit different application needs.

They are reliable, stable, have high precision and repeatability tolerances, and can operate in extreme temperatures. They are also safe to use and do not require hazardous materials. However, they operate at lower speeds and pressures, and there is also a risk of contamination from the air used to drive them.

What are the characteristics of cylinders?

Pneumatic systems use compressed air instead of fluids to create force. Pneumatic cylinders are generally less expensive, simpler, and safer to operate than hydraulic cylinders. Pneumatic cylinders are often used in vacuum pumps and manufacturing equipment.

Hydraulic cylinders

Hydraulic cylinders, on the other hand, use hydraulic fluid to create motion. These cylinders are often used in heavy-duty applications, such as construction equipment, mining, and agriculture. Hydraulic cylinders are capable of generating a lot of force and are often used in applications that require lifting or pushing heavy objects.

One advantage of hydraulic cylinders is their ability to maintain force over long distances, which makes them ideal for applications that require sustained force. However, hydraulic cylinders require more maintenance than pneumatic cylinders because they are prone to leaks and require regular fluid changes. In addition, they are heavier and larger compared to pneumatic cylinders.

Hydraulic cylinders

Other characteristics to consider include the fact that hydraulic systems and the equipment used to power them tend to be larger, more complex, and more expensive than pneumatic systems. This means that maintenance requirements are also more specialized. However, if operated and maintained properly, heavy-duty hydraulic cylinders can do jobs that other equipment cannot.
