Product description
The 21311E1K.TVPB FAG is a spherical roller bearing. 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.
The 21311E1K.TVPB FAG is an X-life type bearing. X-life bearings provide better performance than normal spherical roller bearings due to a special internal construction. Contact surfaces, steel grade and rolling bodies are of a higher quality. X-life bearings combine a higher load capacity with a longer service life. The bearings generate less heat and allow for higher speeds. Finally, X-life bearings allow for longer maintenance intervals compared to normal spherical roller bearings.
