Product Description

The 1217K is an NSK self-aligning ball bearing from the 1217 series: 85 mm bore, 150 mm outer diameter, 28 mm width, tapered bore (K, 1:12 taper). Basic dynamic load rating Cr is 54.5 kN and basic static load rating C0r is 20.8 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.
