The bearing is intended for incorporation in devices effecting linear motions along axles of round section. It comprises a monolithic prismatic cassette and ball chains, disposed inside continuous two-track grooves. These grooves are machined totally in the thickness of the cassette walls, and the non-working sectors of the ball chains are disposed close to the cassette edges and along said edges. The external surface of the cassette is enclosed by the internal surface of the sleeve which is of identical geometric shape. This design makes possible the increase of the number of ball chains disposed in one wall and, hence, of the load-carrying capacity of the bearing.
