Bentonite Grease
Bentonite Grease is an advanced, high-performance lubricant formulated with inorganic clay-based thickener. Unlike conventional soap-based greases, it provides exceptional stability at high temperatures, making it ideal for applications requiring extreme thermal resistance.
This grease is amber-colored and contains anti-corrosion and extreme pressure (EP) additives, ensuring superior protection for plain and rolling bearings operating under high-stress conditions. It delivers excellent performance even at temperatures exceeding 160°C, provided the re-lubrication schedule is appropriately maintained.
Key Benefits of Bentonite Grease
High-Temperature Resistance: Functions efficiently at extreme temperatures.
Non-Melting Formula: Does not degrade under heat.
Excellent Sealing Properties: Prevents contaminants from affecting machinery components.
Superior EP Performance: Protects against wear and tear under heavy loads.
Corrosion and Oxidation Resistance: Prolongs equipment life.
Reduced Maintenance Needs: Longer lubrication intervals reduce downtime.
Leak-Proof Stability: Maintains consistency in extreme conditions.
Industrial Applications
Many industries actively use Bentonite Grease because it provides superior lubrication and stability.
1. Automotive and Heavy Machinery
Bearings and components exposed to high temperatures.
Plastic injection molding machines.
Lubrication of fans and pumps.
2. Mining and Underground Operations
Plumber blades in drilling equipment.
Lubrication of underground mining machinery.
3. Industrial Manufacturing
Bearings in metal stamping, textile, and paper industries.
Machinery in high-friction applications.
4. Specialized Variants
Bentonite Grease is also available with Molybdenum Disulfide (MoS₂) and Graphite additives to enhance lubrication for heavy-duty and extreme load conditions.
Manufacturing Process of Bentonite Grease
The production of Bentonite Grease involves the dispersion of organophilic montmorillonite clay into a base oil, followed by pre-gelling and controlled heating.
Step-by-Step Process:
Selection of Bentonite Powder: High-quality organophilic montmorillonite clay is used as a thickening agent.
Oil Dispersion: The Bentonite powder is blended with base oil.
Pre-Gelling Process: A dispersant is added while stirring to ensure uniform consistency.
Heating Stage: The mixture is heated to remove excess dispersant, forming a stable grease structure.
