OKS 4220 is a very high temperature grease based on perfluorinated polyether oil (PFPE) thickened with PTFE, for use in food technology at maximum loads and temperatures. It can be used for the grease lubrication of rolling and sliding bearings at very high temperatures, e.g. in tunnel kilns, baking, glazing and drying ovens, hot gas units, reaction vessels, boiler plants, wheels and transport rollers in continuous ovens. Temperature range of use: -40°C - 280°C. Drop point: none. NSF H1 (Reg. 124380).
