This pneumatic cylinder is, single acting, meaning it requires air pressure to extend and has a spring to retract the rod. In idle position, the piston rod is extended. The cylinder adheres to ISO 21287 (also referred to as a compact cylinder), which is a globally accepted and widely used standard. The advantage is that it enables world-wide inter-changeability with other major brands such as Festo, SMC or Norgren. The bore size is 32 mm and it has a stroke length of 20 mm. This cylinder has an operating pressure of 1 to 10 bar (14.5 to 145.04 psi). The piston rod has a M8 threads at the end. The piston contains a magnetic element. This allows precise position feedback of the rod location by mounting (one or more) magnetic sensors, such as reed or hall sensors. The cylinder has the G 1/8 inch port for the air routing. The cylinder can be mounted rigid or flexible with a wide range of mounting options, such as rod swivel joint ends (ISO 8139) or rod fork ends. The cylinder head, foot and tube are made from aluminum and the piston rod is made from stainless steel. The Airtec compact ISO 21287 cylinders are compatible with the following product series: Asco 449, Aventics CCI, Festo ADN, IMI Norgren RA, Parker P1P and the SMC C55 series.
Pros:
- ISO 21287 is globally accepted and interchangeable with other major brands
- Compact cylinders are lightweight and space-saving
- Easy installation of position sensors in the grooved body
- The cylinder is self lubricating and requires little maintenance
Cons:
- Not suited for icy conditions
- Damping, but not adjustable
