Product Description

The 23040 is an NSK spherical roller bearing from the 23040 series: 200 mm bore, 310 mm outer diameter, 82 mm width, cylindrical bore (no K). Basic dynamic load rating Cr is 1180 kN and basic static load rating C0r is 1700 kN (NSK official catalog CAT. No. E1103d; current-generation equivalent 23040CAME4, 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.
