has two rows of rollers, which mainly bear radial loads and axial loads in any direction. High radial load capacity, especially suitable for heavy load or vibration load, but can not withstand pure axial load. The raceway of this kind of bearing outer ring is spherical, so its aligning performance is good, and it can compensate coaxiality error. Mainly used in paper-making machinery, deceleration device, railway vehicle axles, rolling mill rollers, printing machinery, all kinds of industrial reducers.
