IKO NAU4920UU sealed roller bearing
The IKO NAU4920UU is a cylindrical roller bearing supplied with integral seals. It suits maintenance engineers and electricians who need a replacement rolling element for motor shafts, gearboxes or pump housings. The bearing is sold as a single unit in a boxed pack.
Check shaft and housing dimensions before ordering
Verify that the shaft diameter matches the 100 mm bore and that the housing bore accepts the 140 mm outside diameter. Confirm the 40 mm width fits the available axial space and that the sealed design is compatible with your lubrication method. Ensure the operating speed and load ratings meet the application requirements.
Integral seals simplify installation and maintenance
The fitted seals retain grease and exclude contaminants without extra shielding components. This reduces assembly time and extends relubrication intervals in dirty or wet environments. The sealed construction also helps protect adjacent components from lubricant migration.
