Extreme-Pressure Molybdenum Grease Lithium-Based CAS 1317-33-5, for Coupling Bearing Heavy Mining Metallurgy Sliding Surface
This extreme‑pressure lithium‑based molybdenum grease is a heavy‑duty industrial lubricating grease. It uses lithium soap as thickener, blended with molybdenum disulfide solid lubricant and extreme‑pressure additives. The grease withstands heavy shock and fluctuating loads encountered on mining and metallurgical machinery. It protects couplings, rolling bearings and sliding metal surfaces, reduces metal wear under harsh dusty conditions and extends the service life of key moving components for h
Product DetailsExtreme‑Pressure Molybdenum Grease Lithium‑Based CAS 1317‑33‑5, for Coupling Bearing Heavy Mining Metallurgy Sliding SurfaceThis lithium‑based extreme‑pressure molybdenum grease is produced from refined mineral base oil, lithium‑soap thickener, finely ground molybdenum disulfide powder and compounded extreme‑pressure, anti‑wear and anti‑oxidant additives. Molybdenum disulfide features layered lamellar crystal structure, which can form a firm solid transfer film on metallic contact faces under high contact pressure. When the fluid grease film breaks temporarily due to sudden shock or peak overload, this solid protective coating still sustains boundary lubrication and prevents direct metal‑to‑metal scuffing.
For shaft couplings of mining and metallurgy machinery, the grease is applied on elastic coupling pins, gear coupling tooth surfaces and connecting friction interfaces. It alleviates abrasion generated by frequent torsional shock during power transmission. For rolling and plain bearings operating under heavy radial and impact loads, the grease fills the clearance inside bearing assemblies, reducing wear of rolling elements, raceways and cages. On large‑size sliding surfaces including swing mechanisms, guide shoes and slide beds on metallurgical processing lines, the lubricating layer mitigates frictional loss during reciprocating movement.
Mining and metallurgy working environments feature heavy dust, mineral debris and intermittent high operating temperature. The grease exhibits good mechanical stability and resists softening under sustained mechanical shearing. The antioxidant composition slows thermal‑oxidative degradation of the grease base, delaying hardening and carbon residue formation after long‑term service.
It is suitable for initial filling during equipment overhaul and periodic re‑greasing for mine conveyor bearings, crusher couplings, rolling‑mill sliding supports and heavy metallurgical transport mechanisms. Proper filling quantity must be controlled; excessive grease volume inside bearing housings will generate extra viscous friction and raise operating temperature.
This grease shall not be blended with other types of greases. Incompatible mixing will break down the thickener structure, cause sedimentation of molybdenum disulfide particles and weaken extreme‑pressure anti‑wear performance. Store in tightly sealed original containers within cool, dry indoor warehouse. Avoid prolonged high‑temperature storage to maintain uniform filler dispersion, ensuring reliable heavy‑duty lubrication for couplings, bearings and sliding surfaces of mining and metallurgical machinery.
