Application

KLUBERsynth 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.

KLUBERsynth 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

KLUBERsynth 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. KLUBERsynth GEM 4 N is miscible with mineral oils. However, for the KLUBERsynth GEM 4 N oil to deliver its full performance, any residues of a previously used mineral oil should not exceed 5 % in quantity. For use at permanent temperatures of 80 °C max., seals made of NBR may be used. For higher temperatures, seals made of FKM should be chosen. It should be noted that elastomers from one or several manufacturers can behave differently; therefore tests should be performed. For checking the contact pattern during running-in, the inspection paint KLUBERtop P 39-462 Spray (Art. No. 081295) can be used.
