IKO NAU4911UU Cylindrical Roller Bearing

This IKO NAU4911UU cylindrical roller bearing is a precision rolling element designed for machinery requiring high radial load capacity.

Suits sealed radial-load applications

This bearing suits applications needing a sealed 80x55x25mm cylindrical roller unit. It is not for buyers requiring tapered roller profiles or thrust-load optimised designs. Builders needing different bore sizes or open configurations should look at alternative specifications. The sealed design limits suitability for relubrication intervals.

Questions about this item

What shaft diameter matches the 55 mm bore of this IKO NAU4911UU bearing?

The bearing has a 55 mm bore, so it fits a shaft of that diameter; check the shaft tolerance class required for your application.

Will the 80 mm outer diameter and 25 mm width fit the housing I use for older NAU49 series bearings?

This model is 80 mm outside diameter by 25 mm wide; compare those dimensions with your existing housing to confirm interchangeability.
