Lubricant films that separate moving surfaces transmit power as traction force between those surfaces. The stresses associated with this traction force can be high enough to cause micro-fracturing in carbon-graphite, a phenomenon known as blistering. The viscosity and the composition of the lubricant film change the magnitude of the traction forces. A test machine was designed to measure the traction behavior and Theological properties of the types of mineral oils and synthetic oils that are commonly in contact with mechanical face seals. The test machine can also be used to assess fluids used in other rolling/sliding contacts such as variable ratio traction-drives for automobiles.
