ABSTRACT:
A follower nut assembly is attached to a load carrying nut all of which is threaded onto a ball screw of a drive actuator. The actuator drive causes a load attached to said load carrying nut to be translated to a fully extended position. At about the fully extended position, a run-off end without threads of the ball screw is positioned in the load carrying nut. This causes the translating force to be fully applied to a follower nut which is normally shear pinned to the load carrying nut. Because of the inertia of the load, the follower nut shears the pin and then rotates within a cage of the follower nut assembly. The translation of the load stops when the shear pin is broken. A thrust bearing is positioned between the follower nut and the load carrying nut to provide the necessary support when the load is fully extended.
