NU204W

Cylindrical Roller Bearing

Bore d20 mm
Width B14 mm

Product Features

NSK cylindrical roller bearing (NU204 series), model NU204W: 20 mm bore, 47 mm OD, 14 mm width, NU type, W pressed-steel cage
Basic dynamic load rating Cr 31.5 kN, basic static load rating C0r 22.6 kN (NSK official catalog; current-generation equivalent NU204E, Cr/C0r figures above are taken from that higher-capacity current design)
Limiting speed approx. 13000 min⁻¹ (grease), 16000 min⁻¹ (oil)
no ribs on inner ring, two ribs on outer ring; inner ring can float axially, no axial load capacity; line contact between rollers and raceways gives high radial load capacity and low friction, suited to high-speed heavy-duty drives

Product Description

The NU204W is an NSK cylindrical roller bearing from the NU204 series (NU type): 20 mm bore, 47 mm outer diameter, 14 mm width, W pressed-steel cage. Basic dynamic load rating Cr is 31.5 kN and basic static load rating C0r is 22.6 kN (NSK official catalog CAT. No. E1103d; current-generation equivalent NU204E, Cr/C0r figures above are taken from that higher-capacity current design). 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.
