Product Description

The N211W is an NSK cylindrical roller bearing from the N211 series (N type): 55 mm bore, 100 mm outer diameter, 21 mm width, W pressed-steel cage. Basic dynamic load rating Cr is 71.5 kN and basic static load rating C0r is 62.5 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.
