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 wwell as bidirectioinal axial load.
Self-aligning roller bearings to cage is divided into :stamped steel reinforced cage(suffix E).stamping steel plate cage (suffic CC) glass fiber reinforced polyamide cage (suffic TVPB) machined brass two-piece cage (suffix MB) machied 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 .
Application Field :
Spherical roller bearings can be used on vibrating/oscillation screen, gearbox, reducer, crusher, agricultural machinery, mine machinery, coal mine machinery, papermaking machinery, reduction gears,railway vehicle axles, roling mill gearbox bearing machinery ,woodworing machinery, various industrial reducers, vertical belts seat self-aligning bearings.
