Product Description

The N220W is an NSK cylindrical roller bearing from the N220 series (N type): 100 mm bore, 180 mm outer diameter, 34 mm width, W pressed-steel cage. Basic dynamic load rating Cr is 225 kN and basic static load rating C0r is 217 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.
