Can you post a picture of the set up as it is currently run? The forces in pneumatics are kind of strange as there are a lot of efficiency issues involved. The angle of attack on the cylinder is a major one. You should get more than enough force to pull 50 lbs. We have used a 2" cylinder to lift people before to demonstrate the forces involved.

Thus, the effective area for retracting is 0.307 square inches.

Check your math on that one, don't trust someone else with it every time.


You'll lose some in friction, efficiency, and actual air pressure available. But in no way should you have an issue creating 50 lbs of force.

Check your plumbing, check your air availability, and check the angle you are applying force at. If all of those check out, try a different cylinder as that one isn't doing what it should.
