Key Points
- Mining lubricants must operate under extreme load, contamination, and temperature conditions.
- Excavators, mining dump trucks, and conveyor systems require greases and oils with high load capacity and environmental resistance.
- Open-pit mining activities, underground operations, and mineral processing equipment require lubricating solutions that ensure operational continuity and component longevity.
- Proper machinery lubrication reduces unplanned downtime, maintenance costs, and wear on critical components.
- MOLYKOTE® lubricating solutions are a key factor for operational continuity in modern mines.
Mining and quarrying operations push equipment to the limits of their capabilities. From the scorching heat of open-pit sites to the challenging underground environments, mining machinery must withstand extreme conditions.
The size of today’s mining equipment, combined with extreme load capacities and hostile operating environments, create lubrication challenges that can only be met by advanced industrial lubricants.
MOLYKOTE® lubricants are formulated for extreme loads and offer efficient performance under conditions that would test even the most robust machinery.
Lubricants designed for the most complex mines and quarries
Modern open-pit mining requires the use of large mechanical equipment capable of operating reliably in difficult environments. These include:
- Heavy excavators working in extreme temperatures ranging from winter cold to summer heat.
- Huge mining trucks (or mining dump trucks) that carry loads pushing bearing systems to the limit.
- Conveyor systems that operate continuously in dusty environments
These machines all require specialized lubrication solutions capable of withstanding these extreme conditions while maintaining optimal performance.
MOLYKOTE® lubricants resist crushing, sliding, and water washout, extending the life of equipment and reducing unwanted downtime and maintenance costs.

Comprehensive lubricating solutions for the mining sector
Our complete range of industrial lubricants MOLYKOTE® addresses all lubrication challenges encountered in mining operations, from surface excavation to underground processing systems.
High-performance mining lubricants protect against shock loads, reversal speeds, and sudden pressures, significantly extending the life of components and equipment.
Lubricants for open-pit mining
Applications in open-pit mining present some of the most challenging lubrication environments in the industry.
Excavators pose a particular challenge, with open gears requiring products capable of withstanding shock loads, dirt contamination, and extreme weather conditions.
The electrical systems of these massive machines are equally critical and require protection from moisture, contamination, and corrosion to ensure reliable operation.
Mining dump trucks must support enormous loads while operating under conditions of constant contamination and temperatures that vary drastically. I Wheel bearings of these vehicles require lubricants with exceptional load capacity and environmental protection, while reducers require thermal stability and protection from extreme pressures for reliable operation in continuous heavy-duty cycles.
Key applications of lubricants for open-pit mining include:
- Open gears and electrical systems of excavators.
- Wheel bearings and reducers of mining dump trucks.
- Bearings, pins, and bushings of front loaders.
- Conveyor belt systems.
Lubricants for processing equipment
Processing equipment such as SAG mills, ball mills, and kilns present some of the most extreme lubrication challenges in the mining sector.
These large machines generate extreme pressures and temperatures during operation, requiring assembly pastes and compounds specialized to maintain their protective properties under these extreme conditions.
Seals and feed chutes require compounds that offer excellent sealing properties and resist the abrasive effects of processed materials. I Guide systems benefit from anti-friction coatings that reduce wear and maintain smooth operation even in contaminated environments.
Components on which mining industry lubricants are applied include:
- Bolts of the outer and inner lining of SAG mills and ball mills.
- Kiln components and feed systems.
- Guide systems and bearing assemblies.
Seal and chute applications.
Lubricants for underground operations
Underground mining operations face additional challenges, with higher levels of humidity and limited access for maintenance, creating environments where lubricant reliability is even more critical.
Fans, blowers, and pumps that provide essential ventilation and water management services require bearings capable of operating reliably for long periods with minimal maintenance.
Transport equipment in underground operations, including various conveyor systems used to move personnel and materials, require mining industry lubricants capable of operating reliably in confined and often damp underground environments.
Air compressor systems, essential for powering tools and pneumatic equipment in all mining operations, require specialized lubricants capable of withstanding the unique challenges of compressed air systems.
Applications of mining industry lubricants in underground operations include:
- Bearings for fans, blowers, and pumps.
- Pins and bearings for transport equipment.
- Pulley systems and winches.
- Applications with air compressors.
Lubricants for maintenance and repair operations
Maintenance and repair operations require specialized products for:
- assembly procedures;
- disassembly procedures;
- metal protection;
- component cleaning.
These applications often involve equipment that has been subjected to extreme operating conditions, requiring products capable of penetrating contamination and providing effective protection during reassembly.
Lubricant applications for mining industry maintenance include:
- Assembly and disassembly operations with specialized pastes.
- Applications on O-rings and valve seals requiring chemical compatibility.
- Cleaning and protection of metals during storage.
- Maintenance and restoration of electrical contacts.
