Klüber Lubrication has introduced Klübersynth GE 4 80 W 140, a fully synthetic high-performance gear oil based on polyalphaolefin (PAO) designed to provide high stability and protection even under shock loads, according to the company. The product 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 teeth and rolling bearings. The low foaming tendency and anti-corrosive properties of the product enable problem-free gear operation, the company says. Klübersynth GE 4 80 W 140 offers a longer service life than conventional mineral oils due to its aging and oxidation resistance. As a result, service intervals are extended and maintenance costs are reduced. High-performance gear oils from Klüber Lubrication can be used in spur, bevel and hypoid gears, particularly if API GL4 or API GL5 is required. Klübersynth GE 4 75 W 90 is approved by several gear manufacturers like IG Watteeuw, Voith Turbo, Siemens-Flende, Stadler Rail, Bombardier, CAF and the German railway operator Deutsche Bahn.
