Product Description

The 2216 is an NSK self-aligning ball bearing from the 2216 series: 80 mm bore, 140 mm outer diameter, 33 mm width, cylindrical bore (no K). Basic dynamic load rating Cr is 54 kN and basic static load rating C0r is 19.9 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.
