This SMC stainless-steel NCM Series air cylinder has a round body, basic-style mounting, and is double acting. The air cylinder (also called a pneumatic cylinder) has a stainless-steel body to help resist corrosion and scaling, and it comes with a single piston rod. The double-acting air 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. It has nitrile butadiene rubber (NBR) seals to contain air and help protect the barrel and piston rod. The air cylinder has basic-style mounting and includes a mounting nut to hold brackets (sold separately) in place. The maximum pressure of the pneumatic cylinder is 250 pounds per square inch (psi), and it has a temperature range of 40 to 140 degrees F. This non-repairable air cylinder is suitable for a variety of general purpose 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.
