There is an ultimate art of precision forging technology
that Ooka has reached over a long time period of time.
O-oka’s precision forging gear is used in various applications such as EV, engine, transfer case unit, etc.
By the intergation of several parts into one piece, O-oka enable to create shape such as internal teeth bottom face, asymmetric tooth thickness and omitted teeth, which are difficult for conventional machining. O-oka puts all technology into one piece.
