Product Description

The 7306BW is an NSK angular contact ball bearing from the single-row 7306 series: 30 mm bore, 72 mm outer diameter, 19 mm width, 40° contact angle, W pressed-steel cage. Basic dynamic load rating Cr is 34 kN and basic static load rating C0r is 19.3 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.
