Spherical roller bearings

Dealing with very heavy radial and axial loads in applications prone to misalignment or shaft deflections? Meet the challenge with SKF spherical roller bearings, whose high load carrying capacity and ability to accommodate misalignment help you obtain low maintenance costs and long bearing service life.

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 SKF spherical roller bearings are SKF Explorer 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 suffix K)
- a taper 1:30 (designation suffix K30)


CC, CA and E design bearings.

CC design bearings

- have two stamped window-type steel cages, an inner ring without flanges and a floating guide ring centred on the inner ring
- are indicated in the product table by the designation suffix C or CC
- are indicated in the product table by the designation suffix 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 flange on both sides and a floating 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 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 suffix CA
- are indicated in the product table by the designation suffix 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 flanges and a floating 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 suffix E
- have an optimized internal design for increased load carrying capacity


Annular groove and lubrication holes

- CC and CA design bearings are available with an annular groove and three lubrication holes in the outer ring (designation suffix W33) or three lubrication holes in the outer ring (designation suffix W20)
- SKF E design bearing have an annular groove and three lubrication holes as standard. This feature is not identified in the bearing designation (no designation suffix).
