Maxtop Heavy Duty Industrial Gear Oil (L-CKD) is used in heavy-duty industrial gears and can effectively protect the gears from running smoothly under heavy load conditions. Heavy Duty Industrial Gear Oil uses a highly refined paraffin-based base oil with a high viscosity index and a variety of additives such as high-quality extreme pressure, anti-wear, oiliness, anti-oxidation, anti-corrosion, anti-rust, and defoaming agents. It is carefully balanced and selected through ultra-long weathering aging tests. It is refined to produce no sludge and sediment, less color change, less viscosity change, less acid value increase, and no significant change in extreme pressure performance.
