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 (fig. 1). The centre point of the sphere in the outer ring raceway is at the bearing axis. Therefore, these bearings are self-aligning (fig. 2) 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.

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 during manufacture, as well as the surface finish of all contact surfaces. Main factors which influence spherical roller bearing performance include, but are not limited to:

Symmetrical rollers 

Symmetrical rollers self-adjust (fig. 3), providing optimal load distribution along the roller length. This keeps stresses low under all load conditions and extends bearing service life.


Roller tolerances 

The rollers in an SKF spherical roller bearing are manufactured to extremely tight dimension and form tolerances. Each roller is practically identical in size and shape to the other rollers in the set. This optimizes load distribution over the rollers to maximize bearing service life.


Special roller profile 

The roller profile determines the stress distribution in the roller/raceway contact area. The special profile distributes loads more evenly along the rollers and prevents stress peaks at the roller ends to extend bearing service life (fig. 4).


Self-guiding rollers and a floating guide ring between the two rows of rollers 

Self-guiding rollers reduce friction and frictional heat (fig. 5). A floating guide ring guides unloaded rollers so that they enter the load zone in the optimal position.


Cages 

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


Adapter sleeve – Tool and accessory selector

By simply selecting the combination of a bearing and sleeve, the program selects the correct tools and accessories to enable the bearing to be mounted and dismounted including:

  • HMV hydraulic nut

  • Pump options for the HMV nut, both for feeler gauge and Drive-up Method

  • Pump options for mounting using the oil injection method

  • Required extension pipes to enable the use of the SKF Oil Injection Method

  • Feeler gauge type

  • Lock nut and washer

  • Spanner type to tighten locking device
