1. A surgical fastener applier comprising:
a housing containing a compartment therein;
an elongated member extending distally from the housing;
a first jaw and a second jaw adjacent a distal portion of the elongated member, at least the first jaw movable with respect to the second jaw to clamp tissue between the first and second jaws;
a fastener firing mechanism positioned within the housing, the fastener firing mechanism movable between a first position and a second position, wherein in the second position, the firing mechanism effects firing of fasteners into the tissue clamped between the first and second jaws; and
a power pack removably loadable into the compartment, the power pack having a first motor and a first engagement member removably engageable with the fastener firing mechanism within the housing when the power pack is loaded into the compartment, the first engagement member movable axially in response to rotation of a first screw operatively connected to the first motor, and at least one bearing on opposing sides of the first screw to limit one or both of radial movement and axial movement of the first screw, wherein linear movement of the first engagement member effects movement of the firing mechanism from the first position to the second position.
