When the grease is selected according to the bearing load of the traveling reducer, the grease with a small penetration should be selected for the heavy load. When working under high pressure, in addition to the small penetration, it also has a higher oil film strength and extreme pressure function. When selecting grease according to environmental preconditions, calcium-based grease is not easily soluble in water and is suitable for drying and low moisture environments. When selecting the grease according to the working temperature, the main indicators should be the dropping point, oxidation stability and low temperature function. The dropping point can generally be used to evaluate the high temperature function. The actual working temperature of the bearing should be lower than the dropping point of 10-20 °C. Synthetic grease should be used at a temperature below the drop point of 20-30 °C.
Different lubricants are not allowed to be mixed with each other. The position of the oil level plug, drain plug and ventilator is determined by the mounting position.
