A linear slide bearing is disclosed as having a slide block formed in cross section into the shape of letter C, the slide block having a recess on the underside and having an upwardly inclined surface on the upper inner side of one arm and a downwardly inclined surface on the inner side of the other arm; a guide rail having its upper portion formed into a shape similar to the recess of the slide block and having a downwardly inclined surface and an upwardly inclined surface, facing the upwardly inclined surface and the downwardly inclined surface, respectively, of the slide block; a pair of guide covers mounted to the both ends of the slide block; endless tracks formed by the no-load ball holes cut through both arms of the slide block, the load ball grooves semicircular in cross section formed in the upwardly and downwardly inclined surfaces of the slide block, the ball-rotating grooves semicircular in cross section formed in the upwardly and downwardly inclined surfaces of the guide rail, and by the guide groove formed in each guide cover; and a number of balls running through the endless tracks, the ball acting as a series of load ball or a series of no-load balls depending on where they are running in the endless track.
