Grease (Multipurpose, Lithium, Calcium, Complex, etc.) (H3)
Greases are classified by their thickener type, with key features like lithium (all-purpose, high viscosity, good temperature stability), polyurea (high-temperature, long-life), calcium (excellent water resistance for marine use), and aluminum complex (high-temperature, good water resistance) being common examples. The best choice depends on the application, as each grease offers a specific balance of properties like temperature resistance, water resistance, and load-carrying capacity.
Types: (H4)
- Lithium: General-purpose lubrication in automotive and household applications (e.g., door hinges, bearings)
Key Features: (H4)
- Multi-purpose, durable, and high viscosity Good stability against oxidation, corrosion, and wear Higher melting point than calcium-based grease
- Polyurea: High-temperature industrial machinery and electric motors
- Excellent high-temperature stability Good resistance to water, rust, and oxidation Long-life lubricant
- Calcium: Marine and outdoor settings
- Excellent water resistance, ideal for wet environments Good mechanical stability and corrosion protection Often used in low-temperature applications
- High-temperature tolerance and water resistance Good shear stability
- Sodium: Often blended with other greases for better quality
- Good rust prevention Poorer water resistance and oxidation capabilities
- Bentone (Clay): Steel, mining, and ceramic industries
- Excellent for extreme temperatures Good adhesive properties
