SKF - Rolling Bearings

Design considerations
For the bearing systems listed above, angular
misalignment of the shaft relative to the housing
must be kept to a minimum. If this is not
possible, SKF recommends a self-aligning
bearing system comprised of either:
Fig. 7
• spherical roller bearing / CARB toroidal
roller bearing († fig. 6)
• self-aligning ball bearing / CARB toroidal
roller bearing
The ability of this bearing system to accom modate
angular misalignment of the shaft relative
to the housing, as well as axial displacement
of the shaft within the CARB bearing,
avoids induced internal axial loads in the bearing
system.
For bearing systems with a rotating inner
ring load, where changes in the shaft length
are to be accommodated between the bearing
and its seat, axial displacement should take
place between the bearing outer ring and its
housing. The most common combinations are:

• deep groove ball bearing / deep groove ball
bearing († fig. 7)
• self-aligning ball or spherical roller bearing
/ self-aligning ball or spherical roller bearing

• matched single row angular contact ball
bearings / deep groove ball bearing
