Norgren PM/31082  Technical parameters Medium:

Compressed air, without lubrication Working pressure: up to 8 bar Working temperature: -PM / 31000 is 40 ° C to + 70 ° C. Important note: The construction of this air bellows enables operation at an angle of 5 ° to 25 ° Dietop and bottom plates may not be aligned depending on the height of the bellows and the number of turns.

To avoid damage, mechanical stops must be used in both end positions.In order to bring the air bellows back to its minimum height, an external restoring force must be applied.The thrust depends directly on the height of the bellows: with increasing height, the thrust decreases.Since the outside diameter changes during operation, there must be sufficient clearance around the air bellows.
