Most spherical roller bearings are designed with two rows of rollers, allowing them to take very heavy radial loads and heavy axial loads. There are also designs with one row of rollers, suitable for lower radial loads and virtually no axial load. These are also called "barrel roller bearings" or "Tonnenlager" and are typically available in the 202- and 203-series.
The internal design of the bearing is not standardised by ISO, so it varies between different manufacturers and different series. Some features that may or may not exist in different bearings are:
Lubrication features in inner or outer ring
Central flange
Guide ring or center ring
Integrated seals
Cage
Spherical roller bearings consist of a common spherical raceway outer ring and two rows of spherical rollers between the double raceway inner ring. The spherical roller bearings is self-aligning, and can automatically adjust the misalignment caused by the deflection or misalignment of the shaft or bearing seat, and the allowable alignment angle is 1~2.5 degrees. Spherical roller bearings can bear radial load, bidirectional axial load and its combined load, especially the radial load capacity is large, and it has good anti-vibration and impact resistance. It is widely used in iron and steel metallurgical equipment, mining equipment, cement machinery, paper machinery, ships, coal mills, petroleum machinery, engineering machinery, etc.
The Spherical 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 well as bidirectional axial load.
