The 22311MB W33 has a double row roller, with a common spherical raceway in the outer ring, with two raceway in the inner ring and an Angle of relative bearing axis. This ingenious structure make it with automatic self-aligning properties, and therefore susceptible to shaft and bearing box seat Angle error or the influence of shaft bending, suitable for installation error or shaft deflection caused by the Angle error of the occasion. In addition to bearing radial load, the bearing can withstand the axial load of two-way.
