This International Standard establishes a metric series of single rod pneumatic compact cylinders with bores of 20 mm to 100 mm for use of at maximum working pressure of 1 000 kPa (10 bar1)) with and without magnetic function. This series of pneumatic cylinder is not equipped with adjustable cushioning. Therefore, the application is restricted to those systems where adjustable cushioning is not required. Cylinders with bores of 20 mm and 25 mm can be used with end cover mountings in accordance with this International Standard. Cylinders with bores from 32 mm to 100 mm can be used with end cover mountings in accordance with ISO 15552. Piston rod mountings can be used for the different bores in accordance with ISO 8139 and ISO 8140.
