Heavy-Duty High-Temp High-Viscosity Bearing Grease Complex Calcium Sulfonate, for Cement Mining Metallurgy Water-Washed Bearing
This heavy‑duty high‑temperature high‑viscosity bearing grease adopts high‑viscosity mineral base oil and complex calcium sulfonate thickener, combined with premium extreme‑pressure, anti‑oxidant and anti‑rust‑corrosion additives. It features excellent high‑temperature resistance, superior water‑washout resistance and heavy‑load bearing capacity. The grease maintains stable lubricating film when subjected to flushing water and cooling water spray, providing durable lubricating protection for wat
Product DetailsHeavy‑Duty High‑Temp High‑Viscosity Bearing Grease Complex Calcium Sulfonate, for Cement Mining Metallurgy Water‑Washed BearingThis complex calcium sulfonate bearing grease is formulated with high‑viscosity mineral base fluid, complex calcium sulfonate thickener and compound additive package including extreme‑pressure, anti‑wear, anti‑oxidant and corrosion‑inhibiting agents. The special calcium sulfonate thickener system provides inherent excellent water‑resistance, resisting grease loss caused by continuous water splashing and strong water flushing. The high‑viscosity base oil helps to form a thick, robust lubricating film under heavy contact pressure.
When applied to water‑washed bearing positions on cement rotary kiln supporting rollers, mining conveyors and metallurgical rolling equipment, the grease adheres tenaciously to raceways, rolling elements and cage surfaces. Even under continuous cooling‑water spray, washing and heavy shock loads, the lubricating layer is not readily stripped away. Extreme‑pressure additives generate protective boundary films at metal contact points to reduce pitting, scuffing and seizure risks for heavily loaded bearing surfaces.
Working environments of cement, mining and metallurgical plants are characterized by high ambient temperature, heavy dust, moisture and intermittent hot metal radiation. The antioxidant components slow thermal‑oxidative degradation of the grease matrix at elevated temperature. Built‑in corrosion inhibitors deliver effective anti‑corrosion performance when water and mineral impurities penetrate into bearing housings. It reduces abrasive wear triggered by dust contamination.
It is suitable for periodic maintenance re‑greasing of kiln roller bearings, cooling‑zone conveyor bearings, rolling‑mill auxiliary bearings and other water‑washed heavy‑duty bearing assemblies. Appropriate filling amount shall be maintained. Excessive grease filling inside bearing housings will produce churning heat, accelerate thermal degradation and shorten service life.
Do not mix this complex calcium sulfonate grease with lithium‑based, polyurea or PFPE fluorinated greases. Incompatible blending will damage the thickener network, deteriorate water‑washout resistance and weaken high‑temperature heavy‑load performance. Store in tightly sealed original containers inside cool, dry indoor warehouse. Avoid prolonged high‑temperature storage to preserve adhesion and heavy‑duty lubricating performance for water‑washed bearings in cement, mining and metallurgy.
