Spherical roller bearing inner ring with two columns of raceway, for spherical outer ring raceway, the outer ring raceway curvature center and bearing center consistent, with automatic self-aligning properties, generally allowed by the self-aligning for 1 ~ 2.5 ° Angle, is suitable for rotor flexible deformation may occur.
This type of bearing has a larger capacity of radial load bearing and can also bear smaller axial load in either direction, but cannot bear pure axial load. The density of the roller and the raceway of the aligning roller bearing is higher, and the friction is much higher than that of the cylindrical roller bearing. Therefore, generally speaking, the allowable working speed of the aligning roller bearing is lower than that of the cylindrical roller bearing.
This type of bearing can be divided into two basic types, C type and CA type, according to the difference of inner ring with and without baffle and the used holder. C type bearing is characterized by the inner ring with no baffle and the use of steel plate to press the holder.
2000c bearings use symmetrical spherical roller and steel plate stamping cage, inner ring without fixed flange, longer roller, large bearing capacity, moving ring guide roller, good performance of center adjustment.
The 2000cc bearing is an improved type of 2000c bearing, and the friction torque between the improved bearing roller and raceway, roller and retainer is small.
The CA bearing adopts the symmetrical spherical roller and solid retainer, the inner ring belt fastens the small baffle and the movable baffle ring, and the large and super-large double-row adjusting roller mainly adopts this structure type.
Spherical roller bearing has two columns of roller, mainly bear radial load, but also can carry axial load in either direction. Have high radial load capacity, especially suitable for overloading or under vibration loading work, but can't afford to pure axial load. This kind of bearing outer ring raceway is spherical shape, so the self-aligning performance is good, can compensate the alignment error.
