NTN has successfully developed the "Taper Hub Bearing Unit" for pickup trucks and SUVs (multi-purpose sports cars). The size has not changed, the life is extended by 20%, and the rigidity is increased by 7%.
The wheel bearing load of pickup trucks and SUVs is larger than that of cars. Therefore, it is not the ball bearings used in cars, but the tapered roller bearings with higher load capacity and higher rigidity. With the gradual realization of maintenance-free, the above-mentioned vehicles have put forward a requirement for further extending the life of the bearing, and it has been difficult to meet this requirement by improvement by materials and heat treatment.
NTN has radically improved the internal design of the bearing. Maximize the external gear by increasing the effective diameter of the retainer. As a result, the spacing between the rollers is reduced to a level that is only a few milliseconds from contact. By increasing the number of rollers by the maximum limit, the burden on each roller is reduced.
