Self aligning roller bearings have double row rollers, with one shared spherical raceway on the outer ring and two raceways on the inner ring that are inclined at an angle relative to the bearing axis. This clever construction endows it with automatic centering performance, making it less susceptible to errors or shaft bending caused by the angle between the shaft and the bearing housing. It is suitable for situations where installation errors or shaft deflection cause angle errors. This bearing can not only withstand radial loads, but also axial loads acting in both directions.

There are two types of inner holes for self-aligning roller bearings: cylindrical and conical. The taper of the conical hole is 1:30 and 1:12. This type of conical inner hole bearing can be easily and quickly assembled on the optical shaft or stepped machine shaft with a locking sleeve or a detachable sleeve.

The models of self-aligning roller bearings include: self-aligning roller bearings (20000CC type); Conical hole self-aligning roller bearing (20000CCK type); Self aligning roller bearing (20000CC/W33 type); Conical hole self-aligning roller bearing (20000CCK/W33 type); Self aligning roller bearings (20000CCK H-type) installed on the locking sleeve; There are a total of 6 types of self-aligning roller bearings (20000CCK/W33 H-type) installed on the clamping sleeve.

Main uses: papermaking machinery, reduction devices, railway vehicle axles, bearing seats for steel rolling mill gearboxes, steel rolling mill rollers, crushers, vibrating screens, printing machinery, woodworking machinery, various industrial reducers, vertical seat self-aligning bearings.
