Pneumatic cylinders or pistons are mechanical elements that transform the energy of compressed air into kinetic (movement), linear or rotary energy. These cylinders perform movements, linear, rotary and angular movements, feeding and lifting. They have the power to make instantaneous changes of direction.
The function of pneumatic cylinders can be single or double acting. Their diameters range from 6 to 320 mm and they can exert a force of 3 to 55,000 Nw. The speed ranges from 25 mm/sg to 1 mt/sg.
The types of pneumatic cylinders can be the standard type that comply with the ISO-6431 ISO-6432, ISO-21287, ISO-15552 VDMA and CNOMO standards, compact guided cylinders, gripping cylinders, telescopic cylinders, cylinders with hollow stem for vacuum, cylinders turning, rodless cylinders, magnetic cylinders, bellows cylinders, metering cylinders and pneumatic grippers.
The main parts of a pneumatic piston are:
They are simple elements and easy to assemble. It requires little maintenance and is economical to install. Long durability, changing the gasket kit. Pneumatic cylinders can be manufactured from a wide variety of materials and can be used in extreme conditions.
Pneumatic cylinders are safe, do not have explosive characteristics or produce excessive heat. The compressed air used to move the pneumatic cylinders does not generate water hammer, which reduces breakdowns or damage to the equipment. They are used in practically all types of industries, where automation is present.
