ROYCO® C-201 is a brown, fluorosilicone based high temperature grease and spline lubricant using a PTFE type thickener for enhanced load carrying capability. It contains an additive package with antioxidants, corrosion inhibitors and heat stabilizing additives. It is intended for high temperature applications requiring good load carrying capability; typical uses include high temperature spline couplings, bearings, actuators and other aggressive environments from −45 to 260 °C. It offers a wide operating temperature range, excellent low temperature properties, very low evaporation and volatility, and is corrosion and rust inhibited.
