Product Description

The N205W is an NSK cylindrical roller bearing from the N205 series (N type): 25 mm bore, 52 mm outer diameter, 15 mm width, W pressed-steel cage. Basic dynamic load rating Cr is 21.8 kN and basic static load rating C0r is 15.7 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.
