7015 High & Low Temperature Lubricating Grease – High-Temperature Grade
The 7015 High & Low Temperature Lubricating Grease is a premium-performance grease specifically engineered for applications that demand reliable lubrication across an exceptionally wide temperature range. Formulated with synthetic base oil thickened by an organic thickener, and enhanced with carefully selected antioxidant and performance additives, this grease delivers outstanding thermal stability, mechanical durability, and water resistance. It is designed to ensure long-term, stable lubrication for precision components operating under extreme thermal conditions.
Product Overview
7015 High & Low Temperature Lubricating Grease is developed to meet the stringent requirements of modern precision equipment. Its advanced formulation allows lubricated components to operate smoothly from ultra-low temperatures down to –70 °C up to high temperatures of 180 °C, with short-term resistance up to 200 °C. This makes it an ideal choice for applications where conventional greases fail due to hardening at low temperatures or oil separation and degradation at high temperatures.
The grease exhibits a high dropping point, excellent colloidal stability, and strong mechanical stability, ensuring consistent lubrication performance even under continuous operation or vibration. In addition, its superior water resistance allows reliable use in humid or moisture-prone environments.
Key Performance Features
1. Excellent High-Temperature Resistance
With a high dropping point of approximately 297 °C, the 7015 grease maintains structural integrity and lubricating capability at elevated temperatures. This ensures minimal oil separation and stable lubrication in high-speed or heat-generating components.
2. Outstanding High and Low Temperature Performance
The grease retains appropriate consistency and lubricity across a very wide temperature range. Even at extremely low temperatures, it maintains good pumpability and low starting torque, while at high temperatures it resists softening and oxidation.
3. Superior Colloidal and Mechanical Stability
7015 grease demonstrates excellent resistance to mechanical shear, preventing structural breakdown during prolonged operation. This ensures that lubricated parts receive continuous and sufficient lubrication, extending service life and reducing maintenance frequency.
4. Strong Water Resistance
The grease shows excellent resistance to water washout, maintaining its lubricating film even in damp or humid environments. This characteristic makes it suitable for equipment exposed to condensation, moisture, or intermittent water contact.
5. Excellent Oxidation and Chemical Stability
Under oxygen pressure and elevated temperatures, the grease exhibits minimal pressure drop, indicating strong oxidation resistance. This contributes to longer service intervals and stable performance over time.
