Hi Rod
When you isolate the bearing on a router bit you are putting the bearing at zero with fence or to say flush with the fence.
You are taking the bearing out of play so to speak.
Or you want the stock to run true with the bearing and the fence.
The purpose ▼
Some times you don't need to use the bearing and that's when a fence will come it to play or you want to make a smaller cut and just use part of the cutter on the bit.
Let's take a T & G bits (Tongus & Groove Set) the default is 7/16" deep let's say you want a 1/4" deep slot ,you would isolate the bearing in the fence and just use 1/4" of the bit to get what you want.
You have now isolated the bearing.
Definitions of isolate
A substance/item that has been separated/removed from a combined mixture.
Hope this helps
