Questions about this item
What shaft diameter does the 90 mm bore of this 6318 bearing fit?
The 90 mm bore matches a 90 mm shaft, so the buyer must already have a shaft of that exact diameter for the bearing to mount correctly.
Will the 190 mm outer diameter and 43 mm width of this 6318 bearing fit the existing housing I plan to keep?
The housing must accept a 190 mm outside diameter and a 43 mm width; if the current housing matches those dimensions the bearing will seat properly alongside the older hardware.
