An actuator (24) for a ram air turbine system (10) includes a piston rod (42) that is cylindrical in shape and centered about a centerline (A), and stow lock pawls (48) supported by the piston rod (42) and able to move radially. Each of the stow lock pawls (48) has a crown (74) with a crown radius (r2). The actuator (24) further includes a lock bolt (52) extending along the centerline (A) radially within the piston rod (42) and configured to be axially movable within the piston rod (42) between a stowed position and a deployed position. The actuator (24) further includes rollers (57) radially outward from the centerline (A) configured to be guided by the lock bolt (52) and a cylinder (36) having a mating surface (68) with a mating radius (r2). The cylinder (36) is positioned radially outward from the piston rod (42) and configured to be axially movable between the stowed position and the deployed position. A ratio of the crown radius (r2) of the stow lock pawls (48) to the mating radius (r1) of the cylinder (36) is less than 0.98.
