Stainless steel self aligning ball bearing have two rows of balls and a curved raceway in the outer ring. Therefore, the stainless steel bearing can be self-aligning and can withstand the angular error between the shaft and the bearing housing. With the two rings of barrel-shaped rollers, it can absorb high radial forces. It is resistant to corrosion. all components are made of stainless steel, the self-aligning ball bearing is therefore corrosion resistant and hygienic.
