Spherical roller bearings have double row rollers, the outer ring has a shared spherical raceway, and the inner ring has two raceways that are inclined at an angle relative to the bearing axis. Mainly bear radial load, but also can bear axial load in any direction. It has good impact resistance, and generally speaking, the allowable working speed of spherical roller bearings is low. It has the self-aligning performance that other bearings do not have, and the self-aligning performance varies with the bearing size series.

Main types:

CC type.

CA type.

MB type.

E Type.

Among them, the CC type and the CA type are the most widely used.

CA type features：

◆ One-piece brass machined cage, the inner ring has no middle rib, the end face has two small ribs, and the rollers are symmetrical.

◆ Under the condition of limited external size of the bearing, it takes up a lot of internal space, so that the external size and number of rolling elements are limited to a certain extent, thereby reducing the possibility of the bearing to further improve its radial bearing capacity

The main applications:

Papermaking machinery, reduction gears, railway vehicle axles, rolling mill gearbox bearing housings, rolling mill rolls, crushers, vibrating screens, printing machinery, woodworking machinery, industrial reducers.
