Great Wall 7017-1(B) Synthetic High-Low Temperature Grease: Ultimate Wide-Temp Lubrication for Extreme Industrial & Aerospace Bearings

Extreme temperature fluctuation is one of the biggest causes of premature mechanical failure in high-precision rotating equipment. Ordinary industrial greases often harden and cause startup resistance at ultra-low temperatures, while melting, evaporating, or forming carbon deposits under continuous high heat. These defects lead to bearing seizure, abnormal noise, severe wear, and frequent equipment downtime. Great Wall 7017-1(B) Synthetic High-Low Temperature Grease is a premium aerospace-grade synthetic lubricant developed by Sinopec Great Wall Lubricants. Formulated with high-performance synthetic base oil and special organic thickener, combined with multi-functional anti-oxidation, anti-wear, and anti-corrosion additives, it delivers ultra-stable lubrication across an extreme wide temperature range, becoming the ideal long-cycle lubrication solution for high-speed, high-temperature, and cold-field mechanical systems. Widely trusted by global aerospace component manufacturers, heavy industry factories, mechanical maintenance teams, and lubricant distributors, 7017-1(B) fills the performance gap of ordinary greases in extreme working conditions. It serves as a cost-effective imported replacement for high-end wide-temperature grease, perfectly balancing ultra-low temperature fluidity, high-temperature thermal stability, and harsh environment adaptability. This blog systematically introduces its core specifications, technical advantages, and professional application scenarios.

What Is Great Wall 7017-1(B) Synthetic Grease?

Great Wall 7017-1(B) is a professional wide-temperature synthetic lubricating grease designed for extreme-condition rolling bearings. With a uniform and delicate texture, it features NLGI 1-2 consistent hardness and stable colloidal structure. It supports a continuous operating temperature range of-60°C to 250°C, with short-term peak high-temperature resistance up to 300°C. Fully compliant with industry standard SH 0431-92 and military-grade specifications, it is classified as L-XEEEA1-2 grade grease, specially developed for high-speed, high-temperature, and outdoor cold-field precision mechanical equipment.

Different from ordinary lithium greases and general high-temperature greases, 7017-1(B) adopts exclusive synthetic formula with ultra-low evaporation loss and excellent shear stability. It does not harden at ultra-low temperatures or melt and drain at high temperatures, realizing true full-temperature stable lubrication for extreme industrial and aerospace equipment.

Core Technical Performance & Product Advantages

Ultra-Wide Temperature Adaptability (-60°C ~ 250°C) This grease maintains excellent fluidity and pumpability at -60°C ultra-low temperature, ensuring smooth cold startup of outdoor field equipment without stalling or jamming. Under long-term continuous high temperature of 250°C, it avoids melting, oil loss, and dry lubrication, and withstands instantaneous peak temperature up to 300°C, adapting to drastic temperature alternation working conditions.
Excellent High-Temperature Oxidation & Thermal Stability The high-purity synthetic base oil and composite additive system effectively suppress high-temperature oxidation and thermal decomposition. It features extremely low evaporation loss, hardly producing carbon deposits, varnish, or sludge during long-hour high-temperature operation. It keeps bearing interiors clean and greatly extends relubrication cycles and equipment service life.
Superior High-Speed Shear & Mechanical Stability With a stable thickener structure, it resists high-speed mechanical shear and impact load. It will not thin out, throw oil, or fail during long-term high-speed rotation, maintaining uniform and tough lubricating oil film to reduce bearing friction, vibration, and operating noise.
Outstanding Water Resistance & Moisture Adaptability It has excellent water splash resistance and humid environment stability. It effectively resists grease dilution and loss caused by water and steam erosion, suitable for high-temperature and humid workshop environments, ensuring continuous and reliable lubrication performance.
Reliable Anti-Rust & Anti-Corrosion Performance Built-in anti-corrosion formula forms a protective layer on metal surfaces, isolating oxygen, moisture, and corrosive media. It prevents bearing rust and electrochemical corrosion during long-term operation and standby storage, improving equipment environmental adaptability.
High Compatibility & Durability It is compatible with most metal materials and conventional rubber and plastic sealing parts, no swelling, aging, or deformation. With long service life and low maintenance frequency, it effectively reduces overall equipment operation costs.
