Many of SelfLube’s components use graphite. Here is what you need to know about it.

Graphite is ordinary carbon in a highly unusual form, a two-dimensional crystal. Think of graphite as a one-atom thick crystal sheet and a piece of graphite as a stack of these sheets. When you write with graphite pencil lead, you are peeling off graphite sheets and depositing them on a sheet of paper. A similar action takes place in a part embedded with graphite, resulting in very slippery graphite sheets being distributed over the wear surface. This makes graphite an excellent solid lubricant that’s clean, permanent, and economical.
