Klübersynth GE 4 75 W 90 is a polyalphaolefin (PAO) based, high performance, fully synthetic gear oil that provides high viscosity stability and protection even when exposed to impact loads. It is especially suitable for gears in railway vehicles.
This high-performance gear oil offers very high wear load capacity according to API GL-5 and can thus be used in gears that meet API GL-4 and API GL-5 requirements. Thanks to the excellent wear protection it provides for gears and bearings, it supports longer operating life for lubricated equipment and reduces maintenance costs. Thanks to its high micropitting resistance of GFT ≥ 10 according to FVA 54/7, it offers effective protection for gears exposed to high loads and is resistant to this type of damage.
The good viscosity stability of the synthetic base oil prevents thinning of the lubricant film even under high loads. Thanks to the excellent aging and oxidation stability of synthetic base oil, oil change intervals are much longer than mineral oils, thus reducing maintenance costs.
Good low temperature properties ensure reliable functions of gear components even at low temperatures. With its very good anti-foaming and anti-corrosion properties, operating safety is increased in lubricated equipment.
