The primary function of hydraulics is to provide great multiplication of force that is easily transmitted with relatively small mechanical components. A hydraulic cylinder can provide many tons of force at low to moderate speeds, compared to a pneumatic cylinder, which is better at providing low to medium forces at high to moderate speeds, respectively. The empirical product of force and speed is power. Calculating the true power of a hydraulic cylinder requires both variables.
