A sliding door assembly includes a door structure having a channel formed therein with the channel extending in an axial direction of the door structure. A first rotary drive structure is configured for selective rotation about an axis of rotation thereof. The first rotary drive structure includes a first drive body rollably received within the channel of the door structure. An engagement feature is configured to transfer the selective rotation of the first rotary drive structure about the axis of rotation thereof to linear translation of the door structure along the axial direction thereof and relative to the axis of rotation of the first rotary drive structure. The door structure may be formed by an extrusion or pultrusion manufacturing process.
