Is Dry-Lube a finish?
Is Dry-Lube a finish?
(OP)
The specification we are dealing with come from Boeing. The specification states that ALL dimensions are BEFORE finish. The ID of the bearing is coated with .0002-.0005 dry lube. The before dry Lube diameter is .9995-1.0015. IF dry lube is NOT a finish then the end diameter would be in the range of .9985-1.0011.
So the question is "IS DRY_LUBE CONSIDERED A FINISH?"

I would consider dry film lube a coating. however it is a friable coating. in other words it will or can be removed during service.
dim's should apply before dry film lube. In my line of work this is how it is done. don't make it harder on yourself.
All my customer have designed their parts this way. 37 + years.

But if you are looking at a substantial qty of parts, it can't hurt to ask before machining and get this clarified for your particular case.
