SKF spherical roller bearings, SKF bearing catalogue

SKF spherical roller bearings have two rows of 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. 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.

SKF 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.

Basic design spherical roller bearing SKF:

  • 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. 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 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. 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 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). They have an annular groove and three 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

Sealing spherical roller bearing SKF: With the exception of bearings designated with a BS2- prefix, the boundary dimensions of sealed spherical roller bearings are in accordance with ISO 15. Bearings with a BS2- prefix, for example BS2-2214-2CS, are based on 222 E or 223 E series bearings, but are slightly wider to accommodate the seals.

SKF sealed spherical roller bearings have the same features and internal design as basic design spherical roller bearings and are available with a cylindrical bore as standard. Some sizes are also available with a tapered bore or can be supplied with a tapered bore on request.
