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
Application
- 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.
