Product Description

The N204W is an NSK cylindrical roller bearing from the N204 series (N type): 20 mm bore, 47 mm outer diameter, 14 mm width, W pressed-steel cage. Basic dynamic load rating Cr is 19 kN and basic static load rating C0r is 12.7 kN (NSK official catalog CAT. No. E1103d). Cylindrical roller bearings use line contact between rollers and raceways for high radial load capacity and low friction — suited to high-speed, heavy-duty drives such as gear reducers, motors and machine-tool spindles.
