Fully synthetic high-performance gear oil of elevated viscosity reduces maintenance costs for rail vehicles
Klüber Lubrication complements product portfolio for railway gearboxes
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 approx. 130 mm2/s at 40 degree Celsius has proven successful for many years,” explains Thomas Kamprath, Market Manager Rail Industry from 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 degree Celsius. Its product concept corresponds to that of the tried-and-tested Klübersynth GE 4 75 W 90 approved by many OEMs, however has a higher viscosity.”
This high-performance gear oil offers high resistance to scuffing and micropitting as well as very good protection against wear on gear teeth and rolling bearings. The base oils' shear stability prevents the lubricant film from collapsing, which is essential to protect both teeth and rolling bearings.
The product's low foaming tendency and anti-corrosive properties 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 ageing and oxidation resistance. Thus service intervals are extended and maintenance costs reduced.
The high-performance gear oils from Klüber Lubrication can be used in spur, bevel and hypoid gears, especially 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.
