the load acting on the surface due to the size of the wheel hub bearing different characteristic change occurs

Increasing the rotation radius of curvature of the surface of the groove, the rolling bearing can reduce the frictional resistance. However, if the radius of curvature increases, the contact surface pressure between the ball and the plane of rotation between the bearing load will increase. In particular, the rotation, the durability of the bearings will taper roller bearings decrease, thus increasing the radius of curvature of the simple approach has been difficult to achieve. DNT Andes contact position with the ball and rotating the load acting on the surface due to the size of the Slewing bearing different characteristic change occurs, developed the new bearings. Compared with the original, in the contact position of the straight running is increased when the radius of curvature of the trench, and the radius of curvature of the contact position during rotation remains the Slewing bearing same as the original. By this method, when the straight traveling wheel rolling bearing to reduce frictional resistance, it is also to ensure that the same level of durability as the original. It also reduces the product than the original preload range, further reducing the frictional resistance.
       Previously, the company accounted for by reducing wheel bearing friction half of the seal sliding resistance, developed about 15% lower friction wheel bearing seal, and by virtue of the product development market. The development of the use of technology that allows the wheel hub bearing rolling resistance reduced by about 25%. Coupled with a low friction bearing seal design allows maximum reduction of friction when traveling straight 40%. Development of large wind power bearing ranks among the world's most advanced
