CS-series shafts are surface-hardened straight solid shafts made of bearing steel (SUJ-2). Additional processing is possible in areas other than the hardened layer.

SCS-series shafts are surface-hardened straight solid shafts made of martensitic stainless steel (SUS440C) or equivalent material. Additional processing is possible in areas other than the hardened layer. They are suitable for when protection from rust is required.

PCS-series shafts are surface-hardened hollow shafts made of bearing steel (SUJ-2). They offer enormous advantage in lowering system weight and energy consumption. The hollow center of the pipe may also be used for enclosing control equipment cables or oil tubes, therefore enabling compact and elegant system design.

These custom shafts include specially-machined shafts, machined pipe shafts, machined stainless steel shafts, and hard chrome or other surface-treated shafts. They are special shafts made for specific ball bushing applications and have undergone processing such as stepped thread cutting.
