Designs and variants
Spherical roller bearings have 2 rows of rollers, a common sphered outer ring raceway and 2 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. 

Factors influence spherical roller bearing performance
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. Main factors which influence spherical roller bearing performance include, but are not limited to: 
1.Symmetrical rollers
2.Roller tolerances
3.Special roller profile
4.Self-guiding rollers and a guide ring between the 2 rows of rollers
5.Metal cages

Basic design bearings

Depending on their series and size, standard spherical roller bearings are as following basic designs:

CC design bearings have 2 stamped window-type steel cages, an inner ring without flanges and a guide ring centred on the inner ring. The CC design is indicated by the
designation suffix C or CC. Large CC design bearings with the designation suffix EC or ECC have an optimized internal design for increased load carrying capacity.

CA design bearings have a machined double prong-type brass cage, an inner ring with a retaining flange on both sides and a guide ring centred on the inner ring. The flanges
on the inner ring are designed to keep the rollers in place when swivelling the bearing during installation or maintenance. The flanges are not designed to guide the rollers
or accommodate any axial load. The CA design is indicated by the designation suffix CA. Large CA design bearings with the designation suffix ECA have an optimized internal design for increased load carrying capacity.

E design bearings have 2 stamped window-type steel cages, an inner ring without flanges and a guide ring centred on the inner ring (d ≤ 65 mm) or on the cages (d > 65 mm). They have an annular groove and 3 lubrication holes in the outer ring. E design bearings are indicated by the designation suffix E. All E design bearings have an optimized internal design for increased load carrying capacity.

Annular groove and lubrication holes
Spherical roller bearings are available with an annular groove and 3 lubrication holes in the outer ring (designation suffix W33) or 3 lubrication holes in the outer ring (designation suffix W20) . E design bearings have an annular groove and 3 lubrication holes as standard and therefore, the W33 designation suffix is not necessary

Cages

Cages in  spherical roller bearings are an integral part of the bearing internal design. Depending on their internal design, series and size, spherical roller bearings are fitted with 1 of the cages . For additional information about the suitability of cages, refer to Cages and Cage materials .
