Features

  1. Both bearing and housing made of AISI440C stainless steel are superior for corrosion resistance and clean environment.
  2. Aligning function can reduce the stress on the bearing by the error of shaft center and the flexure of the shaft.(SSA and SSXCA types)

  3. The adequate fit is kept between the bearing and the housing because no difference occurs in the amount of expansion and contraction by using AISI440C stainless steel for both components.
  4. Best used for the applications that require precise positioning by the precision finishing. As for SSXCA and SSXC types, shaft can be easily fastened with set screws.
