NTN (NTN) has developed a line when moving up to 40% reduction in friction wheel bearings. As the share of car travel time line a larger proportion, so the wheel bearing is expected to increase fuel efficiency up to 1.5%.

    Increase the radius of curvature of the groove surface rotation can reduce the rolling friction bearings. However, if the radius of curvature increases, the carrying load of steel ball and the contact surface between the rotating surface of the pressure will rise. Especially the rotation, the durability of bearings will drop, so the practice of simply increasing the radius of curvature has been difficult to achieve. DNT Andes plane rotation with the ball and the role of the contact position on the wheel bearings due to load changes of different sizes and characteristics, developed the new bearings. Compared with the original, driving in a straight line of contact location increases the radius of curvature of the groove, while the rotation radius of curvature of the contact position of the original is still the same. In this way, driving in a straight line, the scroll wheel bearings reduce friction, while also ensuring the same level of durability of the original. Than the original products also reduced the scope of pre-compression, further reducing friction.

    Prior to the company by reducing wheel bearing friction about half of the seal sliding resistance, developed around 15% lower friction wheel bearing seals, and by virtue of the product development market. With the development of the technology, the wheel bearing about 25% lower rolling resistance. Combined with a low friction bearing seal design, driving straight up to the frictional resistance can decrease by 40%.
