Abstract
An actuator comprises a housing and a drive tube assembly disposed within the housing. The drive tube assembly includes a drive tube provided with internal threads, a piston nut provided with external threads which threadedly engage the inner threads of the drive tube, and an output shaft connected to the piston nut. A motor rotates the drive tube to cause the piston nut to reciprocate along a length of the drive tube and the output shaft to reciprocate relative to the housing. There are bearings which transmit axial loads from the drive tube to the housing and transmit radial loads from the drive tube to the housing.
