load or not the bit deflects

Then either your bit is bent or your router is bad. If
it happens unloaded then it's not deflecting.

no to both I tried in two routers I still need to try it with
the end bearing and allen screw removed

After reading Bodger's comment, I realized what the problem
is he you don't know what the word "deflection" means.

from thefreedictionary.com: "deflection - the movement of a
structure or structural member when subjected to a load"

(the "structural element" in this case being the router bit).

What you are talking about is (as Bodger said) runout.
He explained the causes of runout. If it changes with the
speed of the router, it could be an unbalanced bit, or it
could be bad bearings - more likely the latter. If it
doesn't change with speed, it's most likely a bent bit.
