ABSTRACT:
A linear motion rolling guide unit in which rolling elements of one side are in four-point contact with raceway surfaces of one of two raceways formed by raceway grooves in a rail and grooves in a casing and rolling elements of the other side are in two-point contact with raceway surfaces of the other raceways. Depending on the direction in which load is applied to the slider, the number of raceway surfaces the rolling elements contact is changed to allow machining errors of the raceway grooves and to give room of the machining accuracy so that even when the casing is applied with an uneven load the slider can slide smoothly on the track rail.
