Questions about this item

Does the ZIBOO RNA6918 needle roller bearing arrive as a single unit or do I need to order the inner ring separately?

The INA RNA6918 is supplied with the inner ring already included in the box, so no separate purchase is required for that component.

How do I know the RNA6918 size is the right one for my shaft and housing?

Match the bearing to a 105 mm shaft diameter, a 125 mm housing bore and a 63 mm width; those three dimensions must correspond to your application drawings.

What does the 105x125x63 mm designation tell me about the load the bearing can handle once installed?

Those figures define the inner diameter, outer diameter and width that set the contact area and radial capacity; consult INA's catalogue for the exact dynamic and static load ratings.
