The concept of the bearing with tapered rollers in an X arrangement positioned in turns towards raceways enables to accommodate axial loads in both directions, radial loads as well as tilting moments.
The tapered shape of rollers can effectively eliminate circumferential speed difference at rolling and prevent contact surfaces from skidding with further benefit of lower wearing the raceways and rollers. Ultimately a longer operational life of the bearing is achieved.
