Grease Usage Precautions of Truck

August 08, 2025

Even if the correct grease is selected, improper use can still affect its performance. Please pay attention to the following details:

"Moderate" instead of "the more the better" for filling quantity:

Excessive filling will increase the stirring resistance of components, intensify heat generation, and even squeeze the grease out of seals (for example, excessive filling in wheel hub bearings will cause oil seal leakage); insufficient filling cannot form a complete oil film, leading to dry friction. Generally, it is appropriate to fill 1/2-2/3 of the component cavity.

Regular inspection and replacement:

Check the condition of the grease according to the maintenance cycle (such as every 50,000-100,000 kilometers or 6 months). If hardening, emulsification (water ingress), blackening (impurity contamination) or loss is found, it should be thoroughly cleaned before refilling.

Keep the filling environment clean:

Before filling, clean the dust and oil stains on the surface of the components, and use special cleaning tools (such as dust-free grease guns) to avoid impurities mixing into the grease (impurities will become abrasives and aggravate wear).

Pre-"preheating" in low-temperature environments:

In cold regions (such as below -20℃ in winter), the grease will thicken due to low temperature. Before filling, the grease can be placed in a warm environment to soften, or choose models with good low-temperature fluidity (such as synthetic grease with a high penetration index).
