克鲁勃GEM 4-220 N,克鲁勃GEM4-220N Klübersynth 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 ａnd advanced 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 be switched 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 FVA 54/7 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 oxidation resistance 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.
