The self-aligning ball bearing has two rows of balls and a common concave sphere raceway in the outer ring . The bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing .
It is particularly suitable for applications in the occasion that with shaft deflections or misaglignment . Additionally , the self-aligning ball bearing has the lowest friction of all rolling bearings , which enables it to keep low temperature even at high speed .
