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.

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.
