Technical Data

Medium: Compressed Air, non-lubricated

Operating Pressure: 8 bar maximum

Operating Temperature:-40°C to +70°C for PM/31000

Important Instructions: The design of these air bellows allows an operation at an angle of 5° to 25°. The top and bottom plate can be out of alignment, depending on the height of the air bellow and the number of convolutions. To avoid damage mechanical stops at both end positions have to be used. To return Air bellows to their minimum height an external return force must be used. The thrust depends directly on the height of the air bellow: When height increases – the thrust decreases. As the outside diameter varies in operation there must be enough clearance around the air bellow.
