The selection of double-acting actuators takes DA series pneumatic actuators as an example. The output torque of the rack-and-pinion actuator is obtained by multiplying the piston pressure (supplied by the air source pressure) by the pitch circle radius (force arm). And the friction resistance is small and the efficiency is high. The output torque is linear for both clockwise and counterclockwise rotation. Under normal operating conditions, the recommended safety factor for double-acting actuators is 25-50%
