Klüberoil GEM 1-680 N
High-performance gear and multipurpose oil based on mineral oil with KlüberComp Lube Technology
Application Klüberoil GEM 1-680 N
Klüberoil GEM 1 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 steel, mining and sugar industries. It is also used for the lubrication of standard worm gears as defined in DIN 3996. Klüberoil GEM 1 N can also be used for the lubrication of plain and rolling bearings, all kinds of toothed couplings, chains, guideways, joints, spindles and pumps.
Performance, Features & Benefits of Klüberoil GEM 1-680 N are:
- High scuffing protection
- Excellent wear protection for gears and rolling bearings
- Good shear stability for reliable lubricant film formation
- High micropitting resistance
- Excellent ageing and oxidation resistance
- Low foaming tendency
- Good elastomer compatibility
- Approvals by numerous gear OEMs

Product Description Klüberoil GEM 1-680 N
Klüberoil GEM 1 N is a high-performance gear and multipurpose oil based on selected mineral oils satisfying the growing requirements and increasing power density of modern gears. Klüberoil GEM 1 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. Klüberoil GEM 1 N clearly exceeds CLP requirements according to DIN 51517-3. Corresponding gears can be switched to Klüberoil GEM 1 N without prior consultation with the gear manufacturer provided the general application notes are observed. Klüberoil GEM 1 N offers high scuffing load capacity of API GL4 if ISO VG 150 or higher is selected. Gears are sufficiently protected against scuffing even at extremely high peak loads, vibrations or oscillations, or if no running-in was performed. 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. Klüberoil GEM 1 N offers a much longer service life than mineral oil-based standard gear 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 anticorrosive 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 Klüberoil GEM 1 N. Leakage and oil contamination are prevented. Klüberoil GEM 1 N is approved by Siemens-Flender, Siemens Geared Motors, FLSmidth MAAG Gears, SEW Eurodrive, Getriebebau Nord, Lenze Gears, Stöber Antriebstechnik, ZAE Antriebssysteme, Moventas, Bonfiglioli, etc. By using Klüberoil GEM 1 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.

Application notes
Klüberoil GEM 1 N can be applied by means of immersion, immersion circulation or injection. The use of drip-feed oilers, brushes, oil cans or suitable automatic lubricating systems is also possible. When using automatic lubricating systems, please note the manufacturer's instructions regarding the maximum permissible viscosity. The low-viscosity varieties are also used for oil mist lubrication. It should be noted that elastomers from one or several manufacturers can behave differently; therefore tests should be performed.
