Needle roller bearing with inner ring
The ZIBOO NA4918 is a needle roller bearing supplied with an inner ring. It measures 90 mm bore, 125 mm outside diameter and 35 mm width. The component is new and sold as a single unit in a box.
Maintenance and repair applications
This bearing suits technicians who need a direct replacement for the NA4918 designation in gearboxes, motors or other rotating equipment. It is not intended for applications requiring a different bore, width or a bearing without an inner ring.
90 mm bore, 125 mm outside diameter, 35 mm width
The critical specification is the 90x125x35 mm envelope with inner ring included. Match these three dimensions and the NA4918 part number exactly to confirm fitment before ordering.

Questions about this item
How much heat does the NA4918 needle roller bearing generate during continuous all-day operation?
As a passive mechanical component the NA4918 needle roller bearing produces no heat of its own; any temperature rise comes from the surrounding shaft and housing under load.
What shaft and housing diameters must I already have for the 90x125x35 mm NA4918 bearing to fit?
You need a 90 mm shaft for the inner ring and a 125 mm housing bore for the outer ring, with the 35 mm width matching the available axial space.
Will the NA4918 bearing interchange with an older bearing that has the same 90x125x35 mm envelope but a different internal design?
If the older bearing shares the identical 90x125x35 mm boundary dimensions it will fit the same shaft and housing, but internal geometry differences may change load capacity and running clearance.
