Product Description

The 22330 is an NSK spherical roller bearing from the 22330 series: 150 mm bore, 320 mm outer diameter, 108 mm width, cylindrical bore (no K). Basic dynamic load rating Cr is 1530 kN and basic static load rating C0r is 1690 kN (NSK official catalog CAT. No. E1103d; current-generation equivalent 22330CAME4, 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.
