Klüber Lubrication, a worldwide manufacturer of specialty lubricants, has introduced Klübersynth GE 4 80 W 140, a fully synthetic high-performance gear oil based on polyalphaolefin (PAO) that offers high stability and protection even under shock loads.
With Klübersynth GE 4 80 W 140, Klüber Lubrication complements its range of efficient high-performance oils for railway gears. “Our fully synthetic railway gear oil, Klübersynth GE 4 75 W 90, with a kinematic viscosity of approximately 130 mm²/s at 40 degrees C, has proven to be successful for many years,” explains Thomas Kamprath, rail industry market manager for Klüber Lubrication. “For applications requiring an elevated viscosity, we developed the new railway gear oil Klübersynth GE 4 80 W 140, which shows a kinematic viscosity of approx. 250 mm²/s at 40 degrees C. Its product concept corresponds to that of Klübersynth GE 4 75 W 90, which is approved by many OEMs, but with a higher viscosity.”
Klübersynth GE 4 80 W 140 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. Klübersynth GE 4 80 W 140 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.
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.
