Why is molybdenum disulfide added to gear oils?

Why is molybdenum disulfide added to gear oils?

Molybdenum disulfide (MoS2), an extremely effective dry lubricant, is added to the base oil to provide extra protection against friction. This compound has been tested in various test equipment to determine its performance characteristics.

What is molybdenum disulfide grease used for?

Moly grease is generally used for high pressure metal sliding against metal situations. Greases containing moly are recommended for roller bearings subjected to very heavy loads and shock loading, especially in slow, or oscillating motion such as found in universal joints and CV joints.

Why is graphite lubricant better than molybdenum disulphide?

Graphite is majorly used as a solid lubricant because of its low friction robustness and behavior. Like MoS2, graphite has a low friction coefficient, but, unlike graphite, it doesn't rely on adsorbed moisture or vapors. … When should you use copper paste, molybdenum disulphide or grease on bolt threads?
