An electrically driven rack-and-pinion steering system (10) of a motor vehicle has: an axially displaceable mounted rack (14) which transmits steering movement to steered wheels of the motor vehicle; an electric drive (20) providing a steering force and interacting with the rack (14); and a housing (12) that receives the rack (14) and a drive element (22) of the drive (20), the drive element (22) engaging with a toothing system (16) of the rack (14). According to the invention, a bearing assembly (30) is arranged on a section (18) of the rack (14) without the toothing system, axially on each side of the drive element (22), having a carrier cylinder (31), on the outer shell surface (42) of which an outer contact seal (44) is arranged and on the inner shell surface of which an inner contact seal (40) is arranged, the contact seals (40, 40 ') being in contact with the outer contact seal (44) and the inner contact seal (40) being in contact with the inner contact seal (40, 40'). 44) seal the housing (12) with respect to the rack (14).
