Self-aligning ball bearing bearing requirements where the rotating system of the dynamic balance precision of the shaft and hole of the installation of the bearing parts is higher than the general requirements of the dimensional accuracy and the position accuracy, especially the verticality of coaxiality and abutment seat hole or shaft, and when considering these problems, also must pay attention to high speed bearing factors in operation and high temperature factors.
The shaft bearing system requires high rigidity, and quality requirements as light as possible, in order to overcome this contradiction, such as can be taken to reduce the surface roughness and surface strengthening measures to improve bearing stiffness, the hollow shaft to reduce the quality of the system etc..
