” Basic pneumatic cylinder are used to provide straight-line, in/out linear movement for a variety of applications. Available as single acting (spring extend or spring return) and double acting styles with single rod or double rod configurations, non-rotating, and precision non-rotating models.
Body styles include crimped, round, or tie rod. Single acting cylinder develop thrust in one direction and have lower air consumption compared with the equivalent size of double acting cylinders. With a double acting air cylinder, air pressure may be alternately applied to provide force in both directions.”
