High-temperature greases from Klüber Lubrication consist of thermally stable, preferably synthetic base oils incorporating organic or inorganic thickeners. The maximum upper operat- ing temperature limit for Klüber’s high-temperature lubricating greases today is approximately 300°C (572°F). For lifetime lubrication, however, Klüber Lubrication recommends operating temperatures which are considerably lower in order to achieve acceptable running times.
