Extreme-Pressure Wide-Temperature Bearing Grease Complex Lithium EP, -30~140℃ for Fan Motor Wheel Bearing
This extreme‑pressure wide‑temperature bearing grease is a complex lithium‑soap thickened EP lubricating grease formulated with refined mineral base oil and high‑performance extreme‑pressure, anti‑oxidant and anti‑rust additives. It possesses excellent wide‑temperature adaptability, outstanding shock‑load resistance and good mechanical shear stability. The grease maintains stable lubricating performance under fluctuating operating temperatures, delivering durable anti‑wear protection for fan bea
Product DetailsExtreme‑Pressure Wide‑Temperature Bearing Grease Complex Lithium EP, -30~140℃ for Fan Motor Wheel BearingThis complex lithium EP bearing grease is compounded with high‑quality refined mineral base fluid, complex lithium‑soap thickener and integrated additive package including extreme‑pressure, anti‑wear, anti‑oxidant and anti‑rust agents. The complex lithium soap framework delivers superior thermal stability compared with conventional simple lithium soap grease. At low‑temperature condition of ‑30℃, the grease retains appropriate fluidity to prevent sharp rise of starting torque. Under continuous operation up to 140℃, it resists premature softening, dripping and structural collapse.
When applied for fan bearings, electric motor rolling bearings and wheel bearings, the grease forms a robust boundary lubricating film on raceways, rolling elements and cage surfaces. When transient shock and heavy peak loads occur, the extreme‑pressure additives react locally on metal contact surfaces to generate protective reaction films, mitigating scuffing, pitting and metal seizure risk.
Under continuous rotary mechanical shearing, the grease maintains stable internal network structure and effectively suppresses oil separation. The antioxidant additive system slows thermal‑oxidative degradation of base oil at elevated operating temperature, extending relubrication intervals. Anti‑rust additives offer reliable corrosion protection for bearing steel against humid air, splash water and condensed moisture encountered in workshop environments and mobile equipment wheel‑end assemblies.
It is suitable for periodic maintenance re‑greasing and initial filling of industrial fan bearings, driving motor bearings and vehicle wheel bearings. The filling volume inside bearing housings must be strictly controlled. Excessive grease filling will produce severe churning friction, raise operating temperature and shorten the effective service life of the lubricant.
Do not mix this complex lithium EP grease with polyurea, calcium‑sulfonate or fluorinated PFPE greases. Incompatible blending will destroy the thickener network, reduce extreme‑pressure performance and narrow the effective working‑temperature range. Store in tightly sealed original containers inside cool, dry indoor warehouse. Avoid prolonged high‑temperature storage to preserve original rheological and EP properties for fan, motor and wheel bearing applications.
