Greases are classified based on their thickening agent, base oil, and performance characteristics. Common types include lithium grease, calcium grease, polyurea grease, and aluminum complex grease. Lithium grease is versatile and widely used in general applications. Calcium grease offers good water resistance, making it suitable for marine and outdoor use. Polyurea grease is favored for its long life and high-temperature stability, often used in electric motors. Aluminum complex grease provides excellent resistance to corrosion and is used in high-temperature, high-load applications.
