Product Description

The 30317 is an NSK tapered roller bearing from the 30317 series: 85 mm bore, 180 mm outer diameter, 44.5 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 380 kN and basic static load rating C0r is 375 kN (NSK official catalog CAT. No. E1103d; current-generation equivalent HR30317J, Cr/C0r figures above are taken from that current design).
