The extend side is the total volume of the cylinder. The retract side is the cylinder volume minus the volume consumed by the ram. That is why it has more power in extend mode than retract. The extend pressure acts on the whole area of the piston. The retract pressure acts on the exposed area of the piston (piston area minus the area used by the ram).
