213xx Series
This bearing type has a solid inner ring, which runs on two rows of symmetrical rollers in a solid outer ring. The outer ring has a concave, spherical raceway. This design compensates for any alignment errors and shaft deflections. Spherical roller bearings can withstand particularly high radial loads. Additionally, they can accommodate axial forces in both directions. These bearings are used in elevators, textile machines, food processing machines, cranes etc.
Suffixe CC-Spherical roller bearing of C design but with improved roller guidance and reduced friction;
Suffixes：
C-Spherical roller bearing with symmetrical rollers and floating central guide ring;
CA-Spherical roller bearing of C design but with two integral inner ring flanges and machined cage;
CC-Spherical roller bearing of C design but with improved roller guidance and reduced friction;
CAC-Spherical roller bearing of CA design but with improved roller guidance and reduced friction;
