Memo:
This bearing is of a separable type with double-half inner rings. Its steel balls are in
contact with the rings at four points, can bear radial load or radial and axial combined
load, and has large load capacity and high limit speed. Compared with deep groove ball
bearings, it has smaller axial clearance to limit the bidirectional axial displacement
of the shaft or the shell when the radial internal clearance is the same
