Description
Klübersynth GEM 4-680 N Synthetic high-performance gear and multipurpose oil with KlüberComp Lube Technology | N° 012237
- 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.
- Temperature range: -30°C to +140°C
- Volume: 20 l canister
- Also available in: 200 l barrel
Benefits for your application
- 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
- Wide service temperature range due to good viscosity-temperature behaviour
- Low foaming tendency
- Energy savings due to optimised friction behaviour
- Good elastomer compatibility
- Approvals by numerous gear OEMs
Applications
- Klübersynth 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.
Application notes
- Klübersynth GEM 4 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.
- Klübersynth GEM 4 N is miscible with mineral oils. However, for the Klübersynth GEM 4 N oil to deliver its full performance, any residues of a previously used mineral oil should not exceed 5 % in quantity.
