| Abstract | In response to the demand for more efficient, faster products using bearings, we JTEKT are continuing the development of highly effi cient bearings. For more effi cient ball bearings, we are advancing the change to resin materials for cages in order to utilize the benefits of resin. We have therefore developed the resin cage, which achieves improved low torque and high speed performance. The low-torque feature of the developed cage reduces the amount of lubricant accumulation inside the bearing, and its high-speed performance raises the cage’s rigidity. In this report, we will introduce the resin cage. |
