Klübersynth GE 4 80 W 140, a fully synthetic high-performance gear oil based on polyalphaolefin (PAO) chemistry, offers high stability and protection even under shock loads.
With a kinematic viscosity of approximately 5.1 in.2/s at 104°F, the gear oil has proven to be successful in the market. For applications requiring an elevated viscosity, Klübersynth GE 4 80 W 140, has a kinematic viscosity of approx. 9.8 in.2/s at 104°F. This product concept corresponds to that of Klübersynth GE 4 75 W 90, which is approved by many OEMs, but with a higher viscosity.
The oil offers high resistance to scuffing and micropitting as well as good protection against wear on gear teeth and rolling bearings. The shear stability prevents the lubricant film from collapsing, which is essential to protect both gear teeth and rolling bearings.
The low foaming tendency and anti-corrosion properties of the product enable problem-free gear operation. It offers a much longer service life than conventional mineral oils, due to the excellent aging and oxidation resistance. As a result, service intervals are extended, and maintenance costs are reduced.
