• CASE 1Face spline (first step)

  

  

  These automotive hub bearings, manufactured at our BAIZOU facility, are installed between the disc brake and suspension components. To ensure proper power transmission, the internal structure is precisely machined with a unique shape. Our facility is the only one of its kind in Japan for automotive hub bearing processing, and we have received orders from overseas hub bearing manufacturers.

• CASE 2Face splinting (second step)

  

  

  These automotive hub bearings, manufactured at our BAIZOU facility, are installed between the disc brake and suspension components.

  Face splines: Conventionally, internal splines (shaft splines) are used to fasten the shaft and housing. Fastening with face splines increases the transmitted torque, eliminates the need for a splined shaft, resulting in overall weight reduction and improved ease of assembly and replacement. Currently, this type is gradually replacing the existing bearings in tire bearings in the automotive industry.
