This compact SMC double-acting CKZT power clamp cylinder has tapped-hole mounting, is equipped for left-side, right-side, or center arm installation, and comes with an inductive proximity switch cassette for connecting to electrical circuits for automation. Airflow enters the clamp cylinder to push the single piston rod up, rotating an attached arm (sold separately) so that it clamps down on objects to hold them in place. When airflow pushes the piston rod down, the arm unclamps and rotates up. Arm attachments can be installed on the left side, right side, or center of the compact clamp cylinder, and models of this clamp cylinder are available with 30-, 45-, 60-, 75-, 90-, 105-, 120-, and 135-degree arm opening angles for applications with different clearance needs. The clamp cylinder's body is made of steel to resist wear, corrosion, and rust. A rubber bumper at the base of the clamp cushions the piston's impact upon unclamping, and seals and a rounded cover protect against weld spatter, dust, and other contaminants. This clamp cylinder comes with an inductive proximity switch cassette (Turck switch) installed for automated pneumatic applications in high voltage welding environments. The cylinder has tapped holes for mounting upright on rigid surfaces. The maximum pressure of the pneumatic clamp is 116 pounds per square inch (psi), and it has a temperature range of 14 to 140 degrees F. The clamp cylinder meets Underwriters Laboratories (UL) 94 flammability ratings for quality assurance and is suitable for holding objects in place during welding and assembly applications in the automobile industry.
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 uses 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 applications in automotive, food processing, material handling, and robotics industry applications, among others.
