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.
The inner hole of the self-aligning roller bearing has two kinds: cylindrical and conical, and the taper of the conical cone hole is 1:30 and 1:12. This kind of conical inner hole bearing is equipped with a tight sleeve or a disconnecting sleeve, so that the self-aligning ball bearing with the conical inner hole can be conveniently and quickly assembled on the optical shaft or the stepped machine shaft.
Mainly cage：
Stamped steel 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), stamping steel cage for vibration occasions (suffix JPA).
Brass cage for vibrating occasions (suffix EMA). The same structure, bearing on the code may be different.
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
