Product Description

The 30304D is an NSK tapered roller bearing from the 30304 series: 20 mm bore, 52 mm outer diameter, 16.25 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 31 kN and basic static load rating C0r is 24.5 kN (NSK official catalog CAT. No. E1103d).
