Self-aligning performance of roller bearings

       When the center line of the shaft does not coincide with the center line of the bearing seat and there is an angular error, or when the shaft is bent or inclined due to force, the axis of the inner and outer rings of the bearing will be deflected. At this time, a self-aligning bearing with a certain degree of self-aligning performance or an outer spherical ball bearing with a seat should be used.
　　Roller bearings are most sensitive to the deflection of the bearing, and the load carrying capacity of this type of bearing under deflection may be lower than that of ball bearings. Therefore, when the shaft stiffness and the support stiffness of the bearing seat hole are low, or when there is a large deflection moment, the use of this type of bearing should be avoided as much as possible.
