Product Description

The 22320 is an NSK spherical roller bearing from the 22320 series: 100 mm bore, 215 mm outer diameter, 73 mm width, cylindrical bore (no K). Basic dynamic load rating Cr is 860 kN and basic static load rating C0r is 930 kN (NSK official catalog CAT. No. E1103d; current-generation equivalent 22320EAE4, Cr/C0r figures above are taken from that higher-capacity current design). Spherical roller bearings use double-row rollers on a spherical outer raceway that self-aligns for misalignment and shaft deflection while carrying heavy radial and bidirectional axial loads — common in gear reducers, conveyor rollers, paper machinery and wind-turbine main shafts.
