| Abstract | Ever increasing productivity through reliability is a requirement for mechanical elements used in industrial applications, where spherical roller bearings are subjected to severe operating conditions. In order to meet the severe application requirements, JTEKT has optimized spherical roller bearings with symmetrical rollers to achieve larger load ratings. Physical testing was completed to evaluate the performance and confi rm the theoretical design. As a result, it was confi rmed that the rollers move steadily, which led to less temperature rise and contributed to both high speed and better axial loading performance. After the bench testing was complete, both the physical evaluation and the theoretical analysis (CAE) show very good correlation. |
