Abstract To achieve carbon neutrality by 2050, it is required to reduce CO2 emission because JTEKT uses large amounts of energy. A lot of energy was wasted in the heat treatment process, especially in atmospheric gas furnaces. therefore, the countermeasures are urgently needed. Because the current heat treatment process is intensive, CO2 emission from logistics in the pre- and post-processes was also an issue. Aiming to move away from atmospheric gas furnaces and reducing logistics processes, a one-piece-flow heat treatment process for ball bearings using induction heating has been developed.
