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 is capable of withstanding radial loads

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.

Application of self-aligning roller bearings

Main applicable retainers: Stamped steel plate reinforced retainers (suffix E, rarely found in China). Stamped steel plate type retainer (suffix CC), fiberglass reinforced polyamide 66 retainer (suffix TVPB), machined brass two-piece retainer (suffix MB). Machined brass integral retainer (suffix CA), stamped steel plate retainer for vibration applications (suffix JPA). Brass cage for vibration occasions (suffix EMA). The same structure may have different codes on the bearings.

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.
