Features
- Both bearing and housing made of AISI440C stainless steel are superior for corrosion resistance and clean environment.
- 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)
- 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.
- 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.
