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, 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 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. (Patents)
