How to Choose the Grease According to the Operating Temperature of the Equipment

To choose the appropriate grease according to the operating temperature range of the equipment, you can refer to the following steps:

First, clarify the upper and lower operating temperature limits of the equipment.

If the operating temperature of the equipment is low, close to or below 0°C, grease with good low-temperature performance should be selected. This type of grease usually uses low-viscosity base oil and special thickener to ensure good fluidity and lubrication properties at low temperatures.

For equipment operating in the normal temperature range (about 0°C to 60°C), general-purpose lithium-based grease can often meet the needs. They have better overall performance and cost performance.

When the equipment operating temperature is high (over 100°C), high-temperature grease needs to be selected. High temperature grease generally uses synthetic base oil and high temperature resistant thickener, such as lithium complex base, polyurea base or bentonite base. At the same time, attention should be paid to the dropping point of the grease, which should be significantly higher than the upper operating temperature limit of the equipment to ensure that the grease will not be lost or deteriorated at high temperatures.

In addition, the following factors need to be considered:

1. Equipment load and speed: High-load, high-speed equipment may require grease with more anti-wear and pressure resistance.

2. Environmental conditions: such as whether there is moisture, dust, corrosive media, etc., which will affect the protective performance requirements of the grease.

3. The sealing condition of the equipment: Equipment with poor seals may require grease with better resistance to leakage.
