Spherical roller bearings are generally composed of a spherical outer ring and a double raceway inner ring, one or two cages and a set of spherical rollers.

Spherical roller bearings are generally composed of a spherical outer ring and a double raceway inner ring, one or two cages and a set of spherical rollers. Since the center of the outer ring raceway is the same as the center of the bearing, it has self-aligning performance and can automatically adjust the angle caused by the misalignment of the shaft and the bearing seat. However, the maximum allowable centering angle is generally not more than 3 degrees. under normal working conditions. The allowable centering angle is between 1 degree and 2.5 degrees, if it is sealed, the centering angle is smaller.

According to the current cage structure, spherical roller bearings are divided into three domestic structures, C type, CA type and three structures without suffix, such as 23948CW33, the cage is a stamping cage, 22332CA/W33, the cage The structure is a brass one-piece cage, 23056/W33 is a brass cage, and the cage is divided into two pieces.

SKF23956CC/W33 and 23956C/W33 have the same cage material, and 22336MB/W33 and 22336/W33 have the same structure. SKF and NSK have another cage structure, SKF is E structure, such as 23124E, NSK is 23124EA4 structure, the structure of this cage type product increases the cage strength, the number of rolling elements has been increased, so the bearing capacity is higher. High, but generally replaced by C and CC structures in China.

At present, the spherical roller bearing has a kind of special bearing for vibrating screen. By optimizing the design of the contact tightness of the raceway and the roller and the structure of the cage, it can achieve good temperature rise and life requirements. Such as 22332ZMA, 22332MB and other special bearings for vibrating screens.

Spherical roller bearings currently have a split structure. The inner ring, the outer ring and the cage are divided into two parts. They are connected by a lock ring and a circlip. They are mainly used in occasions where installation, disassembly and maintenance are inconvenient, such as Steel mill converter bearings, 230/530D, 230/750D, 249/800D and other models.

According to the characteristics of spherical roller bearings, the main uses: papermaking machinery, reduction gears, railway vehicle axles, rolling mill gearbox bearing housings, rolling mill rollers, crushers, vibrating screens, printing machinery, woodworking machinery, various industrial speed reducers Machine, vertical self-aligning bearing with seat.
