Self-aligning ball bearings have two structures: cylindrical bore and tapered bore. The cage is made of steel plate, synthetic resin, etc. Its characteristic is that the outer ring raceway is spherical, with self-alignment, which can compensate the errors caused by misalignment and shaft deflection, but the relative inclination of the inner and outer rings should not exceed 3 degrees.
