One base designation across loaded brands
Exact designations rank first. Dimensions, suffixes and other technical differences remain visible so the result is not mistaken for an interchangeability declaration.
“NN3005” across 2 loaded brands
At least two brands share the same bore, outside diameter and width. Use Custom Compare when you want to choose exact suffix variants yourself.
