Spherical roller bearings have two rows of raceways in the inner ring, the outer ring is spherical rolled to, the center ofthe outer ring raceway surface and the center of the bearing. Because of the automatic centering performance, can compensate forthe installation error between the shaft and the shell hole or the shaft delection makes the inner and outer ring tilt. This type ofbearings to withstand radial load capacity is greater, but also can withstand either direction of the axial load. but can not withstand pure axial load. Especially suitable for heavy load or vibration load under the work.
