Rolgard® is a unique high-performance and high-temperature lithium based grease reinforced with PTFE. Rolgard® deposits a fine, tenacious, clinging film on the applied metal surface and the innumerable micro particles of PTFE act as tiny ball bearings that help minimise friction and temperature buildup.
The presence of PTFE in Rolgard® helps propagate smoother movement between movable and interfacing parts even at high speeds and temperatures.
