Product Description

The N305W is an NSK cylindrical roller bearing from the N305 series (N type): 25 mm bore, 62 mm outer diameter, 17 mm width, W pressed-steel cage. Basic dynamic load rating Cr is 36 kN and basic static load rating C0r is 25.2 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.
