This SMC double-acting CK series air clamp cylinder has a round anodized aluminum body and a rod-end clevis bracket that connects to clamping attachments (sold separately) for holding together and releasing work pieces in welding lines and assembly applications. The air cylinder (also called a pneumatic cylinder) uses airflow through air ports in the cylinder barrel to extend and retract the piston rod to produce continued movement. The piston rod connects to an arm or pedestal clamping attachment (sold separately) with a rod-end clevis bracket. When the piston rod extends, the clamping attachment rotates down to clamp two or more work pieces together and hold them steady. When the piston rod retracts back into the cylinder barrel, the attachment unclamps by rotating in the opposite direction. The clamp cylinder's anodized aluminum body resists corrosion and tarnishing, and it has a single carbon-steel piston rod for strength and durability. Air cushioning in the barrel absorbs kinetic energy and dampens the sound of the piston striking the end cap, and nitrile butadiene rubber (NBR) seals contain air and help to protect the tube and piston rod. This air cylinder comes "switch ready" with a magnet sensor installed for connecting to electrical circuits for pneumatic automation. The clamp cylinder has clevis mounting with a preinstalled clevis pin and cotter pin to secure its body to stationary surfaces. The maximum pressure of the pneumatic cylinder is 145 pounds per square inch (psi), and it has a temperature range of 14 to 140 degrees F. This non-repairable air cylinder is suitable for welding pieces of sheet metal together for use in automotive manufacturing.
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.
