The self-aligning roller bearing has a double row of rollers, with one common spherical raceway in the outer ring and two raceway in the inner ring and inclined at an Angle relative to the bearing axis. This ingenious structure makes it self-aligning, so it is not easy to be affected by the Angle of shaft and bearing box on the error or shaft bending, suitable for installation error or shaft deflection caused by Angle error. The bearing can bear radial load as well as bidirectional axial load.
Self-aligning Roller Bearings to cage is divided into: stamped steel reinforced cage (suffix E, few in China). Stamping steel plate cage (suffix CC), glass fiber reinforced polyamide cage (suffix TVPB), machined brass two-piece cage (suffix MB), machined brass integral cage (suffix CA), vibration stamping steel plate cage (suffix JPA). Vibration occasions brass cage (suffix EMA), the same structure, bearing code or have different.
