Dry Powder Graphite Lube Extra Fine (Tube) Graphite has been used as a lubricant since pretty much the industrial revolution. You might have used it to make your Pinewood Derby car go faster.

By combining broken nanodiamonds with molybdenum disulfide layers, they've produced a self-generating, very-low-friction dry lubricant with hundreds of applications that lasts practically forever.

Materials suitable for dry bearings include polymers and polymer composites, carbon graphite, ceramics, and wood.

A graphite-based dry lubricant better tolerated the high temperatures but made bearing balls skid and damage the race. The ball bearing was eventually replaced with a graphitemetal solid bearing ...
