A track car system comprising a track (1) and a track car (2) displaceably arranged on the track in the longitudinal direction thereof by means of rolling bodies. On opposed sides the track (1) is provided with a longitudinal and substantially V-shaped track groove (7, 8). The car (2) comprises two continuous paths (13, 14) each having and outwardly open longitudinal V-shaped car groove (17, 18) facing the respective track groove (7, 8). A plurality of rolling bodies in form of both balls (31) and rollers (32) are provided in each of the continuous paths (13, 14). The rollers (32) have a diameter (d2) substantially equal to the diameter (d1) of the balls and a length (h) less than the diameter (d1) of the balls.
