21312 E/C3 SKF
Spherical roller bearing
The 21312E/C3 SKF is a spherical roller bearing with an open design. 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.
