This may not actually be correct.

There is more pushing force in the pneumatic cylinder as there is more surface area on the piston being pushed by the air. There is less force when retracting (pulling) due to there being less surface area on the piston face. This is due to the shaft attached to the piston.

While this may not sound like much it can be significant depending on what you are trying to accomplish.
