A rectilinear rolling bearing in which four rods each formed with at least one longitudinal flat are arranged in a group with their longitudinal axes parallel and so spaced and orientated that the flats define a guideway for rollers contained therein. There may be a passageway parallel with the bearing and diverters at each end of the bearing through which the rollers circulate. Successive rollers may be placed with their aces at right-angles to each other and alternate rollers may be replaced by balls of the same diameter.
