Miniature pneumatics or something like that

[odense]

Hi all,
I am looking for miniature pneumatics or any components having the same features of preumatics. I woud like to add pneumatics to front of mobile robots to push objects. Compressing force of the pneumatics is not required as too strong but its size is still problem since I am looking for. Desired size is:
- Diameter: <2.5cm
- Minimum length (shrunk): ~2cm
- Maximum length (slacken): ~7cm
PLEASE let me know if you know where it is selling.

Of course I found some very special preumatics satisfying my requirements but it is too expensive (1000USD per 1) so I am not sure I can find desired preumatics with cheap price. Therefore, I am thinking to produce a device that can do like preumatics but it is much cheaper. It could be produced by rubber balloon with shape such as snake tounge or a balloon in coil spring. So please let me know if you know where I can buy material for those ideas.

Thank you very much, It is actually a lot for my choice. Have you known other companies? I really need quite precise pneumatics for my design that is very small.

It depends on the inch of the stroke you want, do you have any pacific size.

Plus for accuracy I would not want to use pneumatics at all, I would say that they are not as precise as you want them to be.

The retracted length should be 2cm while the stroke required is not less than 4cm (double of retracted length). It is problem.
