How to select grease according to drop point
When choosing grease, the main consideration should be given to the working condition (load, speed, temperature), working condition (continuous operation, intermittent operation, vibration and impact, etc.) and working environment (humidity, temperature, air pollution degree, etc.) of the friction pair.
The operating temperature of the grease should be at least 20-30 degrees below its dropping point
When the temperature is high, the fat with good oxidation resistance, small evaporation loss and high drop point should be selected; When the temperature is low, the fat with low starting moment and small similar viscosity should be selected, such as the fat based on compound oil.
