NTN Corporation (hereafter, NTN) has developed a large diameter deep groove ball bearing for the coaxial e-Axle, a key driving source in electric vehicles (EVs). These bearings are designed to support high speed rotation with a dmn value of 1.5 million and provide more than 50% lower torque compared to standard products. Additionally, the large diameter bearing is resistant to electrical pitting. This product contributes to the reduction in size and weight of coaxial e-Axles. As a result, it enhances the efficiency of the e-Axle and extends the cruising distance of EVs by facilitating high speed rotation while maintaining low torque.
dmn value: An indicator that expresses the rotational performance of bearings and is multiplied bearing pitch circle diameter (mm) by rotational speed (min-1)
