Calcium sulfonate grease is a top lubricant made from a calcium sulfonate thickener, base oil, and special additives. It works well under heavy loads and in extreme conditions, and industries around the world use it for its long life and strong protection.
Composition of Calcium Sulfonate Grease
Épaississant :
Calcium sulfonate soap. It makes a strong, three‑dimensional network that holds oil in place when parts press together.
Huile de base :
Mineral or synthetic oil. It forms a thin film that cuts down friction.
Additifs :
Extreme‑pressure agents, antioxidants, rust inhibitors, and corrosion inhibitors. They help the grease keep working in tough environments.
Key Features and Benefits
Extreme Pressure and Anti‑Wear
The calcium sulfonate thickener protects parts under heavy load and sudden shock. It beats many soap‑based greases in pressure tests.
Stabilité à l'oxydation
This grease stays stable at high heat and lasts much longer than many regular greases, so you need fewer change‑outs.
Rust and Corrosion Protection
The thickener keeps water out and neutralizes acids, so it guards metal parts against rust and corrosion in wet or humid places.
Stabilité mécanique et colloïdale
The grease does not split under movement, and it keeps working even on vibrating equipment.
Large plage de température
It works from –30 °C up to +150 °C, and some types handle even higher heat or colder starts.
Eco‑Friendly
Many formulas break down more in the environment, they are less toxic, and they make less impact on nature.
Applications Across Industries
- Steel and Metallurgy: Bearings in rolling mills, casting lines, and cranes
- Automobile: Chassis joints, wheel bearings, and universal joints in water or salt
- Exploitation minière et construction : Heavy machines, conveyors, crushers in dusty or wet sites
- Paper and Cement: Rollers, bearings, and gearboxes in fast, hot production lines
- Marine and Offshore: Winches, deck gear, and submerged parts that need water resistance
Market Growth Data
The global overbased calcium sulfonate market was worth USD 154.98 million in 2023 and should reach USD 233.03 million by 2030 at about 6% annual growth.

How to Choose the Right Grease
- Load Conditions: Pick higher EP ratings for heavy machinery.
- Plage de température : Match the grease to your equipment’s heat and cold limits.
- Exposure to Water: Use calcium sulfonate when parts see water or salt.
- Environmental Rules: Choose biodegradable formulas when needed.
Always follow your equipment maker’s recommendations and safety rules when you apply grease.
