Product Description

The 1209K is an NSK self-aligning ball bearing from the 1209 series: 45 mm bore, 85 mm outer diameter, 19 mm width, tapered bore (K, 1:12 taper). Basic dynamic load rating Cr is 24.2 kN and basic static load rating C0r is 7.35 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.
