Klübersynth GE 4 80 W 140 Synthetic high-performance gear oil 5L

Klübersynth GE 4 80 W 140 Synthetic high-performance gear oil  | N° 012329Klübersynth GE 4 80 W 140 is a fully synthetic high-performance gear oil based on polyalphaolefin (PAO) offering high stability and protection even under shock loads.It was especially developed for rail vehicle gearboxes operating under high loads. The product is based on Klübersynth GE 4 75 W 90, which has been tried and tested on the market and is approved by many OEMs. Its viscosity, however is higher: SAE 80 W 140.Klübersynth GE 4 80 W 140 offers a very high scuffing load capacity of API GL-5 and can therefore be used in gearboxes requiring API GL-4 or API GL-5. The excellent wear protection of both gears and rolling bearings ensures a long service life of the lubricated components, leading to lower maintenance costs. The oil’s high micropitting resistance of GFT ≥ 10 according to FVA 54/7 offers sufficient protection to gears that are subject to high loads and would normally be susceptible to this type of damage. The product’s low foaming tendency and anti-corrosive properties enable problem-free gear operation.Temperature range: -30°C to +150°C Volume: 5LBenefits for your applicationMaximum protection against scuffing: API GL-5Excellent wear protection for gear teeth and rolling bearingsGood shear stability for reliable lubricant film formationHigh micropitting resistanceExcellent ageing and oxidation resistanceWide service temperature range due to good viscosity-temperature behaviourGood anti-foaming characteristicsEspecially developed for rail vehicle gears subject to high stressesComplements Klübersynth GE 4 75 W 90 with a higher viscosityApplicationsKlübersynth GE 4 80 W 140 was especially developed for the lubrication of spur, bevel and hypoid gears with maximum antiwear and lifetime requirements even under shock loads. It may be used in drive units for rail vehicles, industrial robots, textile machines or metalforming pressesApplication notesThe oil can be applied by means of immersion, immersion circulation or injection lubrication. Drip-feed lubrication as well as application by brush, oil can or automatic lubricating systems are also possible. Technical specifications Lower service temperature -30 °C Upper service temperature 150 °C Colour space  yellow Density, DIN 51757, 20 °C  ca. 0,87 g/cm³ Kinematic viscosity, DIN 51562 pt. 01/ASTM D-445/ASTM D 7042, 40 °C  ca. 250 mm²/s Kinematic viscosity, DIN 51562 pt. 01/ASTM D-445/ASTM D 7042, 100 °C ca. 30 mm²/s Pour point, DIN ISO 3016  <= -35 °C SAE-viscosity grade 80 W 140 Viscosity index, DIN ISO 2909 >= 150 Four-ball EP tester, welding load, DIN 51350 part 2  >= 3000 N Flash point, DIN EN ISO 2592, Cleveland, open-cup apparatus >= 200 °C Information on product safety (Manufacturer, Contact)KLÜBER LUBRICATION MÜNCHEN GMBH & CO.
