Product Description

The 2220 is an NSK self-aligning ball bearing from the 2220 series: 100 mm bore, 180 mm outer diameter, 46 mm width, cylindrical bore (no K). Basic dynamic load rating Cr is 104 kN and basic static load rating C0r is 38.5 kN (NSK official catalog CAT. No. E1103d). Self-aligning ball bearings use double-row balls on a spherical outer raceway, self-aligning for minor shaft misalignment with lower friction and higher speed capability than a spherical roller bearing, at the cost of lower radial load capacity.
