I'm not a sealing expert, but I have the feeling, that it will be hard to find a sealing for the following application:
Sealing a piston with diameter approx. 1.5"
medium: air
velocity of the piston: up to 35 m/s (78mph)
differential pressure: 10 bar
temperature: min. 5F (-15°C) max. 400F...
GregLocock, these values are not arbitrary at all, but of course the values are rounded.
But you are right, we also believe that you cannot meet this specification with a steel spring. What we try to find out is, whether it is possible with a fiber reinforced material or not.
What do you...
Ok. israelkk, I need a coil spring, which has a working travel of approx. 2 1/2" and a spring rate of approx. 400 lb./in. The weight of the spring must be lower than 450g. The spring has to make about 100000 strokes in a highly dynamic mode.
If you can give me a steel spring which meets these...
There is a little shareware tool, which I can recommend for dimensioning calculations and similar technical and engineering calculations. You find it in the net under the URL:

What is special with this calculator is that you can make calculations directly with...
@israelkk: No, a steel spring cannot do the job, we know that for sure.
@TVP: Thanks for the hints, I will check that.
Both of you thanks again for your help,

Thank you all for the input. israelkk is right, I need a composite spring, because steel springs are to heavy for our application. Titanium is too expensive.
TVP, thanks for your link, this is quite what I'm looking for. But this company is located in France. Do you know something similar in...
