moly disulfide grease is a special type of grease that has been designed to help reduce friction on metal surfaces. It contains molecules of molybdenum disulfide which act to form protective layers and prevent metal-to-metal contact. It’s a dry lubricant which can be used on its own or added to lubricating greases. Moly disulfide is a natural compound found in the mineral molybdenite and is refined for use as a lubricant additive.

Typically, it’s mixed with other lubricants to form the moly disulfide grease that we use in equipment. It works well in extreme pressure situations where other lubricants may fail. It’s used in many applications including automotive, industrial, military/aeronautics, mining and construction.

When it is mixed with lubricating oil, it acts as a boundary lubricant to reduce friction between sliding surfaces. It also helps prevent corrosion, oxidation and wear. It’s often mixed with other lubricants such as calcium or tetra-perfluoroethylene (PTFE) to improve its lubricity, especially at lower temperatures.

Graco offers several different types of moly disulfide greases, formulated to work in a variety of environments. Some are meant for extreme pressure situations, while others are designed to be more user-friendly and work in a wide range of temperatures. These are ideal for applications that require a consistent, easy-to-use grease such as automatic lubrication systems. They allow the system to automatically replenish the lubricant without the need for a manual process and ensure that all bearings receive the lubrication they need.
