Spherical roller bearings have double-row rollers, the outer ring has a common spherical raceway, and the inner ring has two raceways that are inclined at an angle relative to the bearing axis. This ingenious structure makes it have self-aligning performance. In addition to the bearing can withstand radial load, it can also withstand bidirectional axial load.
Spherical roller bearings have two rows of rollers, which mainly bear radial load, but can also bear axial load in any direction. With high radial load capacity, it is especially suitable for working under heavy load or vibration load, but it cannot bear pure axial load. The outer ring raceway of this type of bearing is spherical, so its alignment performance is good, and it can compensate the concentricity error.
The models of spherical roller bearings are: spherical roller bearings (type 20000CC); spherical roller bearings with tapered bore (type 20000CCK); spherical roller bearings (type 20000CC/W33); spherical roller bearings with tapered bore (20000CCK/W33 type); Spherical roller bearings mounted on the adapter sleeve (20000CCK+H type); 6 types of spherical roller bearings mounted on the adapter sleeve (20000CCK/W33+H type)
Mainly applicable cage: stamped steel plate reinforced cage (suffix E, very few in China). Stamped steel plate cage (suffix CC), glass fiber reinforced polyamide 66 cage (suffix TVPB), machined brass two-piece cage (suffix MB). Machined brass integral cage (suffix CA), stamped steel cage for vibration occasions (suffix JPA). Brass cage (suffix EMA) for vibration occasions. The same structure may have different codes on the bearings.
Main applications: papermaking machinery, reduction gears, railway vehicle axles, rolling mill gearbox bearing seats, rolling mill rolls, crushers, vibrating screens, printing machinery, woodworking machinery, various industrial reducers, vertical self-aligning bearings.
