Klübersynth GEM 4-220N Synthetic high-performance oil 200L barrel

Klübersynth GEM 4 NKlübersynth GEM 4 N is a synthetic high-performance gear and multipurpose oil based on polyalphaolefin satisfying the growing requirements and increasing power density of modern gears. Klübersynth GEM 4 N includes KlüberComp Lube Technology*, i.e. it is based on especially high-grade raw materials andadvanced additives, enabling maximum performance in the lubrication of all gear components.Klübersynth GEM 4 N clearly exceeds CLP requirements according to DIN 51517-3. Corresponding gears can beswitched to Klübersynth GEM 4 N without prior consultation with the gear manufacturer provided the general application notes are observed.Klüberoil GEM 4 N offers high scuffing load capacity. Gears are sufficiently protected against scuffing even at extremely high peak loads, vibrations or oscillations. The excellent wear protection of both gears and rolling bearings ensures that the service life calculated for the lubricated components is achieved, leading to lower maintenance and repair costs. The oil’s high micropitting resistance of GFT ≥ 10 according to FVA54/7 offers sufficient protection to gears that are subject to high loads and would normally be susceptible to this type of damage.Klübersynth GEM 4 N offers a much longer service life than mineral oils due to the excellent ageing and oxidationresistance of the selected raw materials; thus service intervals can be extended and maintenance costs reduced. The product’s low foaming tendency and anti-corrosive properties enable problem-free gear operation. Freudenberg seals made of 72 NBR 902, 75 FKM 585, 75 FKM 260466 and 75 FKM 170055 are resistant to Klübersynth GEM 4 N. Leakage and oil contamination are prevented.The excellent viscosity-temperature behaviour supports the formation of a sufficient lubricant film across a wide service temperature range, even at elevated and high temperatures. Therefore, a single viscosity grade can cover both low and high temperatures in many applications.The optimised friction behaviour enabled by the carefully selected base oils reduces power loss and improves gear efficiency.Klübersynth GEM 4 N is approved by SEW Eurodrive, Getriebebau Nord, Lenze, Moventas, Bonfiglioli, Rexnord,Hansen, Brevini, Stöber Antriebstechnik, ZAE Antriebssysteme, David Brown, FLSmidth MAAG Gears, etc.Klübersynth GEM 4-320 N is approved for use in wind power plants by Winergy, Moventas, ZF WP, Bosch Rexroth, ACCIONA ENERGY, and many more.By using Klübersynth GEM 4 N you can benefit from a number of advantages that will help you save costs easily and efficiently. We look forward to hearing from you.Content: 200kg drumAvailable in 20kg bucket, 200kg drumBenefits for your applicationHigh scuffing protectionExcellent wear protection for gears and rolling bearingsGood shear stability for reliable lubricant film formationHigh micropitting resistanceExcellent ageing and oxidation resistanceWide service temperature range due to good viscosity-temperature behaviourLow foaming tendencyEnergy savings due to optimised friction behaviourGood elastomer compatibilityApprovals by numerous gear OEMsApplicationKlübersynth GEM 4 N was specially developed for the lubrication of spur, bevel, hypoid and planetary gears that are subject to high loads. Such gears are frequently used in the wind, steel, mining and sugar industries. It is also used for the lubrication of standard worm gears as defined in DIN 3996.Klübersynth GEM 4 N can also be used for the lubrication of plain and rolling bearings, all kinds of toothed couplings, chains, guideways, joints, spindles and pumps, especially in applications where the equipment is exposed to elevated temperatures or pronounced temperature fluctuations.Technical specificationsArticle number12234Marking acc. to DIN 51502CLP HC 220Classification acc. to ISO 12925-1CKC 220Lower service temperature-40 °C / -40 °FUpper service temperature140 °C / 284 °FDensity, based on DIN 51757) at 15 °Capprox. 860 kg/m³Foam test, ASTM-D 892, ISO 6247, sequence I/24 °C<= 100/10 mlFoam test, ASTM-D 892, ISO 6247, sequence II/ 93.5 °C<= 100/10 mlFoam test, ASTM D 892, ISO 6247, sequence III/24°C<= 100/10 mlFlash point, DIN EN ISO 2592, Cleveland, open-cup apparatus>= 200 °CKinematic viscosity, DIN 51562 pt. 01/ASTM D-445/ASTM D 7042, 40 °Capprox. 220 mm²/sKinematic viscosity, DIN 51562 pt. 01/ASTM D-445/ASTM D 7042, 100 °Capprox. 27 mm²/sISO viscosity grade, DIN ISO 3448220Viscosity index, DIN ISO 2909>= 150Copper corrosion, DIN EN ISO 2160, 3 h/100 °C1 – 100 corrosion degreeAnticorrosive properties on steel, DIN ISO 7120, method A, steel, 24 h/60 °Cno rust corrosion degreePour point, DIN ISO 3016<= -40 °CAgeing properties, ASTM D 2893, increase in viscosity<= 6 %FZG scuffing test, DIN ISO 14635-1, A/8.3/90, scuffing load stage>= 14FZG scuffing test, based on DIN ISO 14635-1, A/16.6/90, scuffing load stage>= 12FAG FE8 rolling bearing test, DIN 51819-3, D 7,5/80-80, wear of rolling element<= 30 mgFAG FE8 rolling bearing test, DIN 51819-3, D 7,5/80-80, wear of cage<= 200 mgMinimum shelf life from the date of manufacture - in a dry, frost-free place and in the unopened original container, approx.24 months Information on product safety (Manufacturer, Contact)KLÜBER LUBRICATION MÜNCHEN GMBH & CO.
