The role of molybdenum disulfide grease

The proportion of molybdenum disulfide grease for automobiles is very large. From the performance requirements of molybdenum disulfide grease for automobiles, we can see the level of the grease industry in a region. Automotive wheel bearing grease is a semi-solid lubricant that has good adhesion to automotive wheel bearings and provides lubrication for friction points. At the same time, it also has the functions of waterproof, dustproof, anti-corrosion and sealing.

In recent years, automobiles are moving towards low fuel consumption, small size and light weight. The operating temperature of wheel bearing grease will reach 160 ° C and occasionally as high as 200 ° C. Therefore, wheel bearing grease must use long-life, high-temperature-resistant grease. There are two broad types of greases used in automotive wheel bearings: calcium-based greases and lithium-based greases. Although calcium-based grease has good water resistance, pumpability and shear stability, the use of the environment temperature is low due to its existence (should be ℃ 70 ℃); easy to harden at low temperatures, affect viscosity, increase friction resistance and use Short life and other shortcomings have been eliminated in foreign countries, but some parts of automobile wheel bearings in China are still used. With the rapid development of the automotive industry, most of the current automotive wheel bearing lubrication in China has gradually started to use general-purpose lithium-based greases, and the operating temperature range has been extended to -25 to 120 ° C. Compared with calcium-based greases, the lubrication period can be extended. Reduce abrasion and reduce consumption, but there are still problems such as high temperature loss.

Combining the development status of the molybdenum disulfide grease industry and the automotive industry, selecting an excellent performance grease to meet the needs of wheel bearing development is an economic measure to extend the grease change cycle and solve the high temperature loss to maintain good bearing lubrication. Concentrated on research and development, and made excellent quality products that fit the wheel grease:
