Krytox GPL 214 heavy-duty grease is used for high loading or slow speeds. EP greases have high load-carrying capability and good lubrication characteristics under boundary and mixed friction conditions. In addition to the EP additive in Krytox GPL 214 heavy-duty grease, Krytox oil provides adequate EP protection as an oil by itself, due to the viscosity build under load and its unique tribochemistry.
A common test for analyzing EP performance is the Timken EP method, ASTM D2509. The test is performed by applying pressure between a rotating steel cup and a steel block and simulates line contact conditions. Two conditions are observed; the OK Load is the highest load at which no seizing or welding occurs, and it also reflects the load-carrying capability of the lubricant. The
Score Load is the lowest load at which seizing or welding is observed. The scar width, which is the average scar width at the load corresponding to the OK load valve, is also recorded.
Another common test for analyzing EP performance is the Four Ball EP, ASTM D2596. The test is performed by steadily increasing the load on a rotating steel ball in contact with three fixed balls until they seize and welding occurs, which simulates point contact conditions. The lowest load at which this welding occurs is called the Weld Point. From this data, the load wear index (LWI) is calculated, which is a value that relates how well the grease prevents wear when operating below the weld point. For many competing greases, the LWI can generally fall between 50 and 100. Krytox greases typically have an LWI well above 100. This further shows how in addition to extreme condition performance, Krytox™ can also outperform most competitive greases in extreme pressure performance
One of the greatest advantages of using Krytox lubricants is stability in a wide variety of operating conditions and environments. This inert nature is what allows Krytox oils and greases to outlast and outperform competing hydrocarbon products.
