Rolgard is a high-performance, high-temperature lithium-based grease with PTFE reinforcement. Rolgard® forms a thin, adhering layer on the applied metal surface, and the numerous micro PTFE particles work like tiny ball bearings, reducing friction and temperature accumulation. Even at high speeds and temperatures, the presence of PTFE in Rolgard® helps to transmit smoother movement between moveable and interface parts.
