Questions about this item

What shaft diameter fits the 90 mm bore of this NTN 6218 bearing?

The bearing has a 90 mm inner diameter so it mounts on a 90 mm shaft with the appropriate tolerance for the fit class you select.

How do I press the NTN 6218 onto the shaft without damaging the balls?

Apply force only to the inner ring using a sleeve or press tool that contacts the inner race; never press on the outer ring or the cage.
