Ningbo Kaiven Pneumatic Cylinders Co.,Ltd >> Compressed Air Cylinders

The two basic types of compressed air cylinders are single acting and double acting. The single acting cylinder is able to perform an operating motion in only one direction. A single acting air cylinder has air pressure on one side of a piston flange, supplying force and motion, and a spring supplying the return force after pressure release. Single acting cylinders require approximately half the amount of air used by a double acting cylinder for a single operating cycle. A double acting pneumatic cylinder has powered motion in two directions, with pressure on both sides. When a cylinder is pushed out in one direction, compressed air moves it back in the other direction. Air lines running into both ends of the cylinder supply the compressed air. The flow of compressed air is controlled with valves for both single and double acting cylinders. Other types of cylinders include rotary cylinders, impact cylinders and multiple- position, or opposed-thrust, cylinders.

Compressed air cylinders serve applications in a wide range of industries. Some examples include food processing and packaging, metal working, automotive, mining, textile, and forest industries.
