Product Description

The 1205 is an NSK self-aligning ball bearing from the 1205 series: 25 mm bore, 52 mm outer diameter, 15 mm width, cylindrical bore (no K). Basic dynamic load rating Cr is 13.4 kN and basic static load rating C0r is 3.3 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.
