Product Description

The 5305 is an NSK double-row angular contact ball bearing from the 5305 series: 25 mm bore, 62 mm outer diameter, 25.4 mm width, open type. Basic dynamic load rating Cr is 36 kN and basic static load rating C0r is 20.7 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.
