A wing for an aircraft includes a main wing, slat, and connection assembly movable connecting the slat and main wing. The connection assembly includes an elongate slat track, a front end of which is mounted to the slat. The rear end and intermediate portion of the slat track are mounted to the main wing by a roller bearing including a guide rail mounted to the main wing and a first roller unit mounted to the rear end of the slat track and engaging the guide rail. The roller bearing includes a second roller unit mounted to the main wing and engaging an engagement surface at the intermediate portion of the slat track. The slat track profile has upper and lower flange portions and a web portion connecting them. The second roller unit is in a recess between upper and lower flange portions and engages the engagement surface at the upper flange portion and/or at the lower flange portion.
