The present disclosure provides an actuator assembly comprising a ballnut (110) having a helical track (112), an actuator drive unit ("ADU") housing (140) having an ADU track (141), and a ballscrew (220). In various embodiments, the ballscrew (220) comprises a first translation bearing track (222), wherein the helical track (112) and the first translation bearing track (222) form a first translation bearing raceway (451) in which a plurality of first translation bearing balls (421) having a first diameter are disposed, and a second translation bearing track (224), wherein the helical track (112) and the second translation bearing track (224) form a second translation bearing raceway (452) in which a plurality of second translation bearing balls (422) having a second diameter are disposed, wherein the first diameter and the second diameter are not equal.
