Product Description

The 1208K is an NSK self-aligning ball bearing from the 1208 series: 40 mm bore, 80 mm outer diameter, 18 mm width, tapered bore (K, 1:12 taper). Basic dynamic load rating Cr is 21.2 kN and basic static load rating C0r is 6.5 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.
