Product Description

The N209W is an NSK cylindrical roller bearing from the N209 series (N type): 45 mm bore, 85 mm outer diameter, 19 mm width, W pressed-steel cage. Basic dynamic load rating Cr is 56.5 kN and basic static load rating C0r is 47 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.
