IKO NAU4908UU sealed cylindrical roller bearing
The IKO NAU4908UU is a sealed cylindrical roller bearing measuring 62 mm outer diameter, 40 mm inner diameter and 22 mm width. It suits maintenance technicians and machine builders who need a ready-to-fit rolling element for radial load applications. The integrated seals help retain lubricant and exclude contaminants in electric-motor, gearbox or spindle assemblies.
Sealed design reduces relubrication intervals
Factory-fitted seals keep grease inside and debris outside, so the bearing runs longer between service stops. The 4908 series dimensions allow direct replacement in existing housings without machining changes. Buyers who require open bearings for oil circulation or higher speed limits should select a different variant.
Highlights

Questions about this item
How often do the integrated seals on the IKO NAU4908UU need replacement?
The seals are built into the bearing and are not serviceable separately; the whole unit is replaced when seal performance declines.
What is the first limiting dimension under sustained load for this 62 mm outer-diameter bearing?
The 22 mm width governs the contact area, so surface pressure on the rollers reaches its limit before the 40 mm bore or 62 mm outer diameter.
