KOUPER PROSPIN series formulated using extremely hydro-treated mineral base stocks and selected additives to enhance oxidation resistance and provide maximum protection against wear, corrosion and foaming. This supports smooth functioning of the high-speed spindles and extends the oil change intervals. The optimized viscosity-temperature behavior, provides a greater film thickness even at high temperatures. The low friction coefficient helps in reduces power consumption and bearing operating temperatures.
