Description
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.
Klübersynth 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 (tested at 90, 60 and 40 °C) 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 statically and dynamically 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 Siemens-Flender, 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.
