IKO NAU4911 cylindrical roller bearing
The IKO NAU4911 is a cylindrical roller bearing measuring 80x55x25mm. It suits maintenance technicians and engineers who need a direct replacement for this specific part number in electric motor or gearbox assemblies.
Sustained load behaviour
Cylindrical rollers distribute force across a longer contact line than ball bearings, so the unit resists deformation during continuous radial loading. The design suits steady-speed shafts where axial movement is constrained by other components.

Questions about this item
How much heat does the NAU4911 generate during continuous all-day operation?
As a sealed cylindrical roller bearing, the NAU4911 produces negligible heat when properly lubricated and loaded within its 80x55x25mm design limits.
What shaft and housing tolerances must I already have for the 80x55x25mm NAU4911 to install correctly?
The NAU4911 requires a shaft diameter of 55mm and a housing bore of 80mm with standard bearing fits; verify your existing components match these dimensions before fitting.
