Chevron Tegra Synthetic Gear Lubricants are superior quality industrial EP gear lubricants.
The most advanced formulation has been selected to provide superior load carrying and antiwear properties; protection against rust, corrosion, foaming, and oxidation; and excellent demulsibility. This results in outstanding performance in most types of industrial gearboxes, exemplified by the FZG pass stage results of >12.
These products possess very high shear stability even under heavily loaded, high speed conditions in industrial gears.
The low pour point and very good low temperature fluidity of Chevron Tegra Synthetic Gear Lubricants impart improved lubrication during startup at sub-zero temperatures, while their superior viscositytemperature characteristics provide dependable lubrication at high temperatures.
A unique property of the synthetic base oil is a low traction coefficient, resulting in improved gear efficiency, energy savings, less friction, less wear, and lower operating temperatures compared to conventional mineral oil products.
Due to the very high viscosity index, these products provide a much higher oil viscosity at operating temperature than a mineral oil product of the same ISO grade. This results in increased oil film thickness and better antiwear protection for both bearings and gears. Drain intervals can be extended longer than conventional mineral oil products. That means fewer oil changes, reduced maintenance costs, and less used oil disposal.
Applications
Chevron Tegra Synthetic Gear Lubricants are recommended for all types of enclosed industrial gearboxes, especially those running continuously at temperatures up to 107°C(225°F) or exposed to very cold temperatures as low as -46°C(-50°F), or under severe service conditions, such as heavy loads or low speeds. These products also provide excellent protection for bearings operating under similar conditions. They can be problem-solvers for applications where mineral oil products deteriorate too rapidly or lead to premature failures. Chevron Tegra Synthetic Gear Lubricants meet the requirements of:
