13、87:2004IS:78212 O4002(E) I SO 4002 All irthgs ersedevr iiiForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committe
14、es. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Inte
15、rnational Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International S
16、tandards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the su
17、bject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 21287 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 3, Cylinders. BSISO21287:2004IS:78212 O4002(E) iv I SO 4002 All irthgs ersedevrIntroduction In pneum
18、atic fluid power systems, power is transmitted and controlled through a gas under pressure within a circuit. One component of such system is the pneumatic cylinder. This is a device which converts power into linear force and motion. It consists of a movable element, i.e. a piston, and a piston rod,
19、operating within a cylindrical bore. The compact cylinder series without cushioning allows the application of pneumatic cylinders within systems where “normal” pneumatic cylinder series because of their mounting dimensions cannot be used.

20、002 All irthgs ersedevr 1Pneumatic fluid power Cylinders Compact cylinders, 1 000 kPa (10 bar) series, bores from 20 mm to 100 mm 1 Scope 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 pres
21、sure of 1 000 kPa (10 bar 1) ) 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
22、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. 2 Normative referen
