Outstandingly water, media and temperature-resistant lithium/calcium complex-soap based on mineral oils with extreme high load carrying capacity, especially at low speeds and oscillating movements. The mechanically and chemically resistant grease for the lubrication of open gears absorbs vibrations as well as shock and features high protection against wear and tribo-corrosion. It is uniquely adhesive and adheres to the metal surfaces, even when subject to centrifugal loads.
