Product Description

The 2312K is an NSK self-aligning ball bearing from the 2312 series: 60 mm bore, 130 mm outer diameter, 46 mm width, tapered bore (K, 1:12 taper). Basic dynamic load rating Cr is 97 kN and basic static load rating C0r is 28.3 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.
