When it comes to grease, the impression is that everyone is soft and soft. Although there are many types of greases, few people can really distinguish between the different ones. Today, it is suitable for different types of greases to be used for everyone:
1. Calcium-based grease:
Good water resistance, but poor heat resistance, the maximum use temperature is 60 ℃, the price is low. It is mainly used for rolling bearings of various industrial and agricultural machinery such as automobiles, tractors, water pumps, small and medium-sized motors, and lubrication of parts that are easily contacted with water or moisture. Rolling bearings with a temperature range of -10 ℃ to 60 ℃ and a rotational speed of 3000 r/min or less are used in part.
2. Lithium-based grease:
Good heat resistance, water resistance, rust resistance, temperature range -20 to 120 ℃, moderate price. Compared to calcium-sodium based greases, the thickening dose can be reduced by about 1/3, and the service life can be more than doubled.
General purpose greases are widely used in various lubrication parts of trucks. Good high temperature lubrication, meeting the requirements of most trucks, is also the most easily available on the market.
3. Universal lithium grease:
Good heat resistance, water resistance, rust resistance, excellent extreme pressure performance, maximum temperature of 120 °C, suitable for lubrication of high-load mechanical equipment and bearings and gears. fair price. With the addition of antioxidants, rust inhibitors and extreme pressure agents, the range and performance of long-life universal greases are more suitable for automotive grease technology requirements.
