Lubricants for enclosed gears

Foaming
The tendency of an oil to foam reduces its lubricating properties. Klübersynth GEM 4-320 N overcomes this problem with its excellent anti-foaming properties as demonstrated in the Flender foam test. Furthermore, it also fulfills the filtration test requirements of CC Jensen and Hydac.

Micropitting
Operators are often faced with micro pitting, which bears a risk of follow-up failures. With its advanced additives, Klübersynth GEM 4-320 N offers a high micro pitting resistance of load stage ≥ LS 10 (GFT “High”) according to FVA 54/7 over a wide temperature range. Furthermore, it maintains a GFT “High” result even after more than 6 years of use in the gearbox.

Residue formation
Some gear oils contain additives that may break down, form residues and cause problems in operation. Our product has been developed as a combination of carefully tuned pure base oils and advanced additive technologies ensuring minimum residue formation.

Scuffing
Basic wear protection needed for gear oil from teeth rubbing called scuffing, is FZG load stage 12. This product provides protection > load stage 14

Extended relubrication interval
An important requirement from modern gear oils is for it to have a long life and extended relubrication interval. This involves the viscosity to remain stable, high shear stabililty and low tendency to oxidize. GEM 4-320 N shows excellent performance on all these parameters.
