An actuator for a ram air turbine system includes a piston rod that is cylindrical in shape and centered about a centerline, and stow lock pawls supported by the piston rod and able to move radially. Each of the stow lock pawls has a crown with a crown radius. The actuator further includes a lock bolt extending along the centerline radially within the piston rod and configured to be axially movable within the piston rod between a stowed position and a deployed position. The actuator further includes rollers radially outward from the centerline configured to be guided by the lock bolt and a cylinder having a mating surface with a mating radius. The cylinder is positioned radially outward from the piston rod and configured to be axially movable between the stowed position and the deployed position. A ratio of the crown radius of the stow lock pawls to the mating radius of the cylinder is less than 0.98.
