Product Description

The 2205K is an NSK self-aligning ball bearing from the 2205 series: 25 mm bore, 52 mm outer diameter, 18 mm width, tapered bore (K, 1:12 taper). Basic dynamic load rating Cr is 13.6 kN and basic static load rating C0r is 3.45 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.
