Product Description

The 2220K is an NSK self-aligning ball bearing from the 2220 series: 100 mm bore, 180 mm outer diameter, 46 mm width, tapered bore (K, 1:12 taper). 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.
