Product Description

The 2218 is an NSK self-aligning ball bearing from the 2218 series: 90 mm bore, 160 mm outer diameter, 40 mm width, cylindrical bore (no K). Basic dynamic load rating Cr is 77.5 kN and basic static load rating C0r is 28.7 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.
