Product Description

The 22205 is an NSK spherical roller bearing from the 22205 series: 25 mm bore, 52 mm outer diameter, 18 mm width, cylindrical bore (no K). Basic dynamic load rating Cr is 37.5 kN and basic static load rating C0r is 37 kN (NSK official catalog CAT. No. E1103d; current-generation equivalent 22205CE4, 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.
