                BPW Axle beams
                Square, reliable, light – the BPW axle beam. It’s the stable
           H    foundation for a long vehicle life. And in combination                        Air cylinder bracket
                with our brakes and suspension systems, the square axle
                produces axle systems which offer convincing all round
           K    performance with long service lives and maintenance                                   Brake anchor plate

                The BPW square axle beam consists of two high-quality,
                specially rolled “U” sections which are welded together
                inside and out.
                The special feature of the BPW standard axle tube with a
                120 mm axle cross-section is its Q.U.A.D. profile (Quality
                Upgraded Advanced Design). This profile features more
                material at the corner radii and less material in the top
                and bottom areas. As a result, the axle cross-sections are
                reinforced at the points where the force is applied and are
                optimally shaped to cope with the load.
                The Q.U.A.D. profile ensures that the maximum service
                life can be achieved. BPW axle tubes are available
                with various cross-sections and wall thickness values
                depending on the axle load and the application
                conditions.
                BPW axle stubs are forged, quenched and tempered.
                They have two stepped bearing seats.
                The axle stubs and axle tube are flash butt welded
                together to produce the one piece BPW axle beam.
    
    
                In this welding process, the axle tube and the ends of the   Axle beam after flash butt-welding
                axle stubs are heated up to welding temperature by an
                electric current applied at their joining faces, whilst at the
                same time being forced together.
                This produces an absolutely homogeneous connection
                without any inclusions. In contrast to conventional
                welding processes, no filler metals are needed.
                At the same time, the axle beam is given its camber and
                toe-in.                                                 Axle beam after removing the welding flash
