The main characteristics of self-aligning ball bearings are:

(1) The outer ring raceway of the self-aligning ball bearing is part of a sphere, and the center of curvature is on the axis of the bearing. Therefore, the bearing has the function of self-aligning. When the shaft and shell are bent, it can be adjusted automatically. No increase in bearing burden.

(2) Can bear radial load and two directions of the right amount of axial load. But it cannot bear torque load. This kind of bearing has small contact Angle, almost unchanged under axial load, small axial bearing capacity, large radial load capacity, suitable for heavy load, impact load.

(3) Double row self-aligning ball bearings with locking sleeves and locking nuts can be installed at any position on the optical shaft, without the need to locate the shaft shoulder.
