| Abstract | We JTEKT have been developing low friction torque bearings from the viewpoint of environmental issues such as global warming. In particular, we are more advanced than competitor companies regarding the development of low friction tapered roller bearings (TRB), which at JTEKT are called our "LFT series". Furthermore, we have engaged in the development of the new TRB, known as the "LFT-IV", and have achieved a 50 percent reduction in friction torque compared with the previous product ("LFT-II") by utilizing CAE tools. |
