Graphite is a type of stone/rock/metal. When we use graphite we usually put it on something that moves. This is the problem, (not-withstanding that it's messy to use). If there is sufficient pressure on the two parts, that are in a "friction" state, the graphite transfers to the other surface. Hence you now have rock rubbing against rock! It will squeak/groan or what ever, because the friction is high between the two surfaces. This is OLDE technology, that is well passed it's time. There are far better things to use for REDUCING friction. Let's get into, at least, the 20th century! Having been in this business for 30 years, I have found very few applications where graphite was the ultimate answer to the problem. The only one that comes to mind, is bridge caps. And, even this, is, IMHO, more cosmetic, (we expect to see it), rather than friction reduction for the bearing surface of the bridge/wire. Just my take on that stuff.
