Features
- Corrosion Resistance
Both bearing and housing made of AISI 440C stainless steel are superior for corrosion resistance and clean environment. - Aligning function for SSA and SSXCA type
Aligning function can reduce the stress on the bearing by the error of shaft center and the flexure of the shaft.
- Fit
The adequate fit is kept between the bearing and the housing because no difference occurs in the amount of expansion and contraction by using AISI 440C stainless steel for both components. - Mounting
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.

Precautions
Axial load may impair the aligning function, therefore is not recommended.
Please refer to the chart below for the recommended tightening torque.
Refrain from tightening over the recommended torque or using a screw locking adhesive.
They can cause bearings to fail prematurely.
