The raceway of the outer ring is spherical, and the center of curvature is consistent with the center of the bearing. Therefore, the inner ring, the ball, and the cage can rotate freely around the center of the bearing and have self-aligning properties. It is suitable for transmission shafts where the shaft and housing are difficult to center and the shaft is prone to flexure. Because of the small contact angle, the axial load capacity is also small. Generally, stamping cages are used.

Product preview

The permissible alignment angle of the self-aligning ball bearing is about 0.07~0.12 radians (4-7 degrees) under normal load conditions. According to the relevant installation dimensions around the bearing, there are special cases where this adjustment angle cannot be achieved, so please pay attention.

Miniature series: 10x, 12x, 13x
General series: 12xx, 13xx, 22xx, 23xx
A self-aligning ball bearing is a bearing equipped with spherical rolling elements between the inner ring of two raceways and the outer ring whose raceways are spherical. It can withstand large radial loads and at the same time a certain axial load, as shown in Figure 2. The outer ring raceway of this type of bearing is spherical. Therefore, it has self-aligning performance.

The main features of self-aligning ball bearings are:
(1) The outer ring raceway of a self-aligning ball bearing is a part of a spherical surface, and the center of curvature is on the bearing axis. Therefore, the bearing has a self-aligning function and can be automatically adjusted when the shaft and housing are deflected. Does not increase the bearing burden.
(2) It can bear radial load and appropriate axial load in two directions. But it cannot bear moment load. The contact angle of this type of bearing is small, the contact angle is almost unchanged under the axial load, the axial load capacity is small, the radial load capacity is large, and it is suitable for heavy load and impact load.
(3) The double-row self-aligning ball bearing with adapter sleeve and lock nut can be installed at any position on the optical axis, without the need to locate the shaft shoulder. as the picture shows.
