If you want to increase the force of a cylinder without changing supply pressure, what parameter should you adjust?

• A. Increase cycle frequency
• B. Increase piston area
• C. Increase supply temperature
• D. Increase line length

Answer: (B)

The force a pneumatic cylinder can exert at a given supply pressure is determined by the piston area. The basic relationship is Force = Pressure × Area. So, with the pressure fixed, increasing the piston area increases the force proportionally. For example, doubling the bore area doubles the available force, assuming other factors remain the same. The other options don’t raise the force in the same way: increasing how often the cylinder cycles changes speed and throughput, not the static force; raising supply temperature isn’t a reliable method to increase force and can affect performance in other ways; and longer line length can cause pressure drop, which may reduce the force at the piston. Therefore, using a cylinder with a larger bore is the way to get more force without changing the supply pressure.
