Product Description

The 7313BW is an NSK angular contact ball bearing from the single-row 7313 series: 65 mm bore, 140 mm outer diameter, 33 mm width, 40° contact angle, W pressed-steel cage. Basic dynamic load rating Cr is 119 kN and basic static load rating C0r is 77 kN (NSK official catalog CAT. No. E1103d; current-generation equivalent 7313BEAW, Cr/C0r figures above are taken from that higher-capacity current design). Angular contact ball bearings carry radial load together with axial load in one direction; because a radial load produces an axial reaction, two or more bearings are typically matched (DB, DF or DT) — common in machine-tool spindles, pumps and precision drives.
