Spherical roller bearings

Spherical roller bearings have two rows of symmetrical 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.


Bearing features

Accommodate misalignment Spherical roller bearings are self-aligning like self-aligning ball bearings or CARB bearings .


• High load carrying capacity

Spherical roller bearings are designed to accommodate both heavy radial loads and axial loads in both directions .


• Long service life

The rollers are manufactured to such tight dimensional and geometrical tolerances that they are practically identical in a roller set The symmetrical rollers self-adjust, providing optimal load distribution along the roller length and together with the special proile prevent stress peaks at the roller ends.


• Low friction

Self-guiding rollers keep friction and frictional heat at low levels  A loating guide ring guides unloaded rollers so that they enter the load zone in the optimal position .


• Robust

All spherical roller bearings contain strong window- or prong-type cages.




Designs and variants 


Standard assortment

The assortment of SKF spherical roller bearings is the widest available on the market.

The standard assortment includes:

• CC, CA and E design bearings

• sealed bearings

• bearings for vibratory applications

• bearings for wind energy applications


All spherical roller bearings areExplorer bearings and almost all bearings are available with the option of a tapered bore Depending on the bearing series, the tapered bore has:

• a taper 1:12 (designation sufix K)

• a taper 1:30 (designation sufix K30)


CC design bearings

• have two stamped window-type steel cages, an inner ring without langes and a loating guide ring centred on the inner ring.

• are indicated in the product table by the designation sufix C or CC

• are indicated in the product table by the designation sufix EC or ECC for larger bearings and 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 lange on both sides and a loating guide ring centred on the inner ring.

The langes on the inner ring are designed to keep the rollers in place when swivelling the bearing during mounting or maintenance and are not designed to guide the rollers or accommodate any axial load .


• are indicated in the product table by the designation sufix CA

• are indicated in the product table by the designation sufix ECA for larger bearings and have an optimized internal design for increased load carrying capacity


E design bearings

• have two stamped window-type steel cages, an inner ring without langes and a loating guide ring centred on the inner ring (d ≤ 65 mm) or on the cages (d > 65 mm).

• are indicated in the product table by the designation sufix E

• have an optimized internal design for increased load carrying capacity
