At the Toyota Commemorative Museum of Industry and Technology, many of the machine tools that Kiichiro Toyoda used when he started the automobile factory in 1938 are on display. One of them, a 1939 G&H hobbing machine, was investigated and found that the motor was manufactured by Fuji Electric in 1924. The details of this motor are currently under investigation, and inside it used bearings manufactured by SKF in the early 1920s. Upon detailed investigation of this bearing, it became clear that the precision and materials were already comparable to modern bearings, and that in Europe in the early 1920s, bearing manufacturing technology that could be used today had been established.
