GEARMASTER ECO products are based on polar saturated esters and have excellent wetting and cleaning properties (clean gear technology). They provide excellent wear protection and corrosion protection, high thermal stability, high oxidation stability and have a long lifespan.
GEARMASTER ECO products can decrease the oil sump temperature due to their low friction coefficient. They have been used with great success in wind turbine applications worldwide for many years as a high-performance, environmentally friendly gear oil. For example, the results of the FAG four-stage test (the wind turbine test for industrial gear oils created by the Schaeffler Group) demonstrate the excellent wear protection properties of GEARMASTER ECO oils. Their total rating of 1.0 (excellent) reflects the outstanding wear protection properties at different friction, temperature and load conditions.Special AW/EP additives guarantee high scuffing protection and also avoid micropitting failures. Gears and bearings are protected over the full temperature range and a long gearbox lifetime is ensured.
GEARMASTER ECO products are fully synthetic, biodegradable gear oils based with ISO VG 68–680. They are miscible and compatible with mineral oil and polyalphaolefin.
In various tests they give the following results:
 micropitting test FZG GFT: LS >10, high protection;
FZG GFT: C/8.3/+60oC and +90oC: load stage high;
FZG scuffing test: high protection;
FZG A/8.3/90: load stage 14;
FZG A/16.6/140: load stage >12;
FAG wind turbine four-stage test: rating 1.0 (excellent wearprotection, no wear); and FE eight-roller bearing wear test, 7.5/80/80 and 7.5/100/80:no wear.
GEARMASTER ECO products have excellent oxidation stability,thermal stability (passed the SKF WTGU test at +100oC) cleaning properties clean gear technology, filterability and material compatibility. They also have a low foam tendency and excellent air-release properties.
Approvals and references are available from Bosch Rexroth, Flender, Moventas, Winergy (GE) and other leading manufacturers of gearboxes and wind power plants.
