Spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. The centre point of the sphere in the outer ring raceway is at the bearing axis. Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. Spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions. rodamientos
application of Spherical roller bearing
This bearing type has a solid inner ring, which runs on two rows of symmetrical rollers in a solid outer ring. The outer ring has a concave, spherical raceway. This design compensates for any alignment errors and shaft deflections. Spherical roller bearings can withstand particularly high radial loads. Additionally, they can accommodate axial forces in both directions.
The bearing is designed for use in vibrating machines such as road rollers, saw frames and vibratory screens. This particularly robust bearing can withstand very high loads, speeds, accelerations, and centrifugal forces. Dynamic angular misalignments up to 0.15° can be supported. Also, the bearing is resistant to dirt and moisture. This bearing guarantees top performance under demanding operating conditions.

spherical roller bearing Designs and Structures
CTN1: Nylon retainer.
C: Stamped steel retainer and strengthened symmetric rollers;
offers considerably higher load ratings than conventional designs for a broad range of applications and long service life.
CA: Alternative design of C design;
Precision-machined one-piece brass retainer and strengthened symmetric rollers;
used to exchange with C design, especially for large size.
MB: Two-piece precision-machined brass retainer and strengthened symmetric rollers;
equivalent to C design in load capacity.
CC: steel cage, replace traditional brass cage.
E: Third generation design.
The bearing contact is completely optimized and has improved stress distribution;
offer much longer service life than normal designs.
Bearing performance is not only determined by load or speed ratings. There are a number of other factors that contribute to bearing performance. To a large extent, performance is influenced by the geometry of the rollers, raceways and cages, the heat treatment, as well as the surface finish of all contact surfaces.
