Abstract
A ballnut assembly is provided in which a locknut (20), which is normally unloaded becomes loaded in the event of failure of a primary load path. This loading causes relative motion between locking nut (24) and the threads of a shaft (8) such that on clearance there between is eliminated. This causes frictional forces to initiate a lock-up of the locknut.
