Product Description

The 22226K is an NSK spherical roller bearing from the 22226 series: 130 mm bore, 230 mm outer diameter, 64 mm width, tapered bore (K, 1:12 taper). Basic dynamic load rating Cr is 820 kN and basic static load rating C0r is 940 kN (NSK official catalog CAT. No. E1103d; current-generation equivalent 22226EAKE4, 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.
