Klübersynth GEM 4-150 N LWC

Nº de artículo: 012334 Excellent wear protection for gears and rolling bearings Good shear stability for reliable lubricant film formation Reduced maintenance efforts and costs due to high micropitting and scuffing protection Excellent ageing and oxidation resistance Wide service temperature range enabled by good viscosity-temperature behaviour Increased reliability due to low foaming tendency and good elastomer compatibility Energy savings because of optimised friction behaviour Low water content in line with requirements of ABB Marine Ports for Azipods

Klübersynth GEM 4 N LWC 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 LWC 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 LWC clearly exceeds CLP requirements according to DIN 51517-3. Corresponding gears can be switched to Klübersynth GEM 4 N LWC without prior consultation with the gear manufacturer provided the general application notes are observed. Klübersynth GEM 4 N LWC offers high scuffing load capacity. Gears are sufficiently protected against scuffing even at extremely high peak loads, vibrations or oscillations. 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 offers sufficient protection to gears that are subject to high loads and would normally be susceptible to this type of damage.

Klübersynth GEM 4 N LWC offers a much longer service life than mineral oils due to the excellent ageing and oxidation resistance of the selected raw materials. The product's low foaming tendency and anti-corrosive 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 Klübersynth GEM 4 N LWC. Leakage and oil contamination are prevented.

The excellent viscosity-temperature behaviour supports the formation of a sufficient lubricant film across a wide service temperature range, even at elevated and high temperatures. Therefore, a single viscosity grade can cover both low and high temperatures in many applications.

The optimised friction behaviour enabled by the carefully selected base oils and additives reduces power losses and improves application efficiency. This leads to lower oil temperatures and reduced energy consumption. Examination on a test rig showed that for spur gears a reduction of the oil temperature from 85 °C with conventional oil (mineral oil) to 80 °C with Klübersynth GEM 4 N LWC is possible. Numerous field tests carried out in various facilities using gearboxes proved that specific energy savings in the area of 1% - 6 % can be attained and operating costs reduced accordingly.

Klübersynth GEM 4 N LWC is approved and recommended for lubrication of bearings in Azipods from ABB Marine Ports. The oil meets the specific performance, cleanliness and low water content requirements of ABB Marine Ports.
