Spherical Roller Bearings

Spherical roller bearings are self-aligning bearings, comprising solid outer ring with a concave raceway, solid inner ring and two rows of barrel rollers with cages. 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.


Various types exist that differ by internal design, including bearings with a tapered bore inner caliber. The bearings are easily mounted on the shaft with an adapter or un-mounting sleeve, and are used in many industrial machines for their high load capacity.


Designs

Depending on their series and size, standard spherical roller bearings are manufactured to one of following basic designs:

  • 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 CC.

  • 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.

  • 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.
