Product Description

The 7303BW is an NSK angular contact ball bearing from the single-row 7303 series: 17 mm bore, 47 mm outer diameter, 14 mm width, 40° contact angle, W pressed-steel cage. Basic dynamic load rating Cr is 16.3 kN and basic static load rating C0r is 8 kN (NSK official catalog CAT. No. E1103d). 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.
