Product Description

The 32318 is an NSK tapered roller bearing from the 32318 series: 90 mm bore, 190 mm outer diameter, 67.5 mm width. Tapered roller bearings use a tapered inner ring, rollers and outer raceway so a single bearing carries combined radial load and axial load in one direction; inner and outer rings are separable, giving flexible mounting and clearance adjustment. Basic dynamic load rating Cr is 555 kN and basic static load rating C0r is 590 kN (NSK official catalog CAT. No. E1103d; current-generation equivalent HR32318J, Cr/C0r figures above are taken from that current design).
