Part no.2311 which provided by Japan NSK Factory, self-aligning ball bearings, which has two rows of balls and a common concave spheroid raceway in the outer ring. The bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing. Therefore the NSK bearings are particularly suitable for applications where considerable shaft deflections or misalignment are to be expected.
