Automatic candidate selection
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.
Dimensions verified
“NKX45” 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.
