Product Description

The 5306 is an NSK double-row angular contact ball bearing from the 5306 series: 30 mm bore, 72 mm outer diameter, 30.2 mm width, open type. Basic dynamic load rating Cr is 45 kN and basic static load rating C0r is 28.1 kN (NSK official catalog CAT. No. E1103d). Inner and outer rings are each integrated into one piece, equivalent to a back-to-back pair of single-row angular contact bearings — a single unit carries bidirectional axial load, radial load and moment loading, common in machine-tool spindles, printing machinery and pumps as a fixed-end bearing.
