This SMC double-acting NCQ8 Series air cylinder has a compact aluminum body and through-hole mounting for securing to rigid surfaces. The double-acting air cylinder (also known as a pneumatic cylinder) uses airflow through two air ports on opposite ends of the cylinder barrel to push out and retract the piston rod to produce continued movement. The air cylinder has an anodized aluminum body to help resist corrosion and tarnishing, and it comes with a single piston rod. It has nitrile butadiene rubber (NBR) seals to contain air and help protect the barrel and piston rod. The air cylinder has through-hole mounting for secure installation on rigid surfaces. The maximum pressure of the pneumatic cylinder is 200 pounds per square inch (psi), and it has a temperature range of 15 to 150 degrees F. This non-repairable air cylinder is suitable for compact linear applications.
Pneumatic actuators fall into two classes: linear and rotary. Linear actuators move objects in straight lines, while rotary actuators turn objects, or rotate them in varying directions. Air cylinders (also called pneumatic cylinders), the most common type of linear actuators, use pressurized air to pull and push piston rods in and out of cylinder barrels. This motion moves mechanisms connected to the rods, or (for detached items) directs or blocks travel using rod-attached plates. Air cylinders execute pushing, pulling, lifting, lowering, pressing, and stopping functions, and they come in several different body types, including round, compact, tie-rod, guided, slide, and clamp. Pneumatic cylinders can be either single acting, with one compressed air port to push the rod in a single direction and a spring to return the rod, or double acting, with two compressed air ports on opposite ends of the cylinder to both extend and retract the rod. For quieter piston operation, air cylinders can come with cushioning in one or both ends of their barrels. Several mounting styles are available both for attaching the air cylinder ends to moving components in a pneumatic system and for mounting to rigid surfaces. Air cylinders are used in industrialized automation tasks in automotive, food processing, material handling, and robotics applications, among others.
