A linear jack includes a first sleeve disposed at least partially within a second sleeve (the first sleeve and the second sleeve collectively a high speed assembly), a third sleeve disposed at least partially within the first sleeve, and a translating screw disposed at least partially within the third sleeve (the third sleeve and the translating screw collectively a low speed assembly). The linear jack further includes a fourth sleeve fixed to the second sleeve and configured to translate therewith. The fourth sleeve extends over the third sleeve and transfers axial loads between the second sleeve and the third sleeve to extend the high speed assembly together with the low speed assembly from an outer case of the linear jack.
