7016 High/Low Temperature Lubricating Grease
Wide-Temperature, Water-Resistant Grease for Aviation Electric Machines
Product Overview
7016 High/Low Temperature Lubricating Grease is a high-performance synthetic grease specifically developed for bearings operating under wide temperature ranges and demanding service conditions. It is formulated using synthetic base oil thickened with an organic gelling agent, combined with carefully selected antioxidant and performance-enhancing additives. This balanced formulation ensures excellent lubrication reliability at both extremely low and high temperatures, while maintaining outstanding mechanical stability and water resistance.
Manufactured in accordance with Q/SH303 119, 7016 grease is designed to meet the strict requirements of aviation electric machines, including generators, motors, inverters, and other precision rotating equipment. It is also suitable for various industrial rolling bearings exposed to high temperatures, moisture, or long operating cycles.
Key Performance Characteristics
Excellent High and Low Temperature Performance
7016 grease provides stable lubrication across a broad temperature range from –60 °C to +200 °C, with short-term resistance up to 250 °C. Its high dropping point of 315 °C ensures grease structure integrity at elevated temperatures, while low apparent viscosity at low temperatures enables smooth start-up and reduced bearing torque.
Superior Mechanical and Colloidal Stability
The organic thickener system offers excellent resistance to mechanical shear and structural degradation. This ensures consistent grease consistency, reduced oil separation, and reliable long-term lubrication for precision bearings operating under vibration or continuous rotation.
Good Water Resistance
7016 grease demonstrates strong resistance to water washout, allowing bearings to operate reliably in humid or damp environments. This characteristic is especially important for aviation and industrial applications where condensation or moisture exposure cannot be avoided.
Outstanding Oxidation and Chemical Stability
Advanced antioxidant additives protect the grease against oxidation and thermal degradation. Long-term oxidation testing shows no pressure drop, confirming excellent chemical stability and extended service life.
