You know how cat hair gets everywhere, right?…well, get some moly grease on your filthy digits and see what happens. Get some on mama or the baby and dang….

Aside from being difficult to remove from your skin and clothing, grease manufactured with molybdenum disulfide (aka moly) is a fantastic product that serves its purpose very well. Used for situations where metal slides against metal under extreme pressures, moly is an excellent choice for chassis parts and wheel bearings of construction, mining and other off highway equipment. Additionally, CV joints, heavily loaded plain and roller bearings in industrial applications, and fifth wheels are prime applications for this non user-friendly, sticky, annoying superstar of a grease.

Silvery and black in nature, Moly is extracted from molybdenite ore and then purified for use in lubrication. Due to its geothermal origins, moly withstands both pressure and heat very effectively. Because of its affinity to metals and its platelet like structure, moly creates an armor like overlapping coating of protection on metals. Used in the correct application, moly grease is an engineering marvel!

According to the International Molybdenum Association (yes, that’s a thing), a number of unique characteristics differentiate moly from other solid lubricants:

  • An inherent low coefficient of friction
  • A film forming structure
  • A very high yield strength
  • Stability in the presence of most solvents

When choosing a grease, always try to check the owner’s manual and follow the guidelines within it. Not doing so could cause problems; for example you wouldn’t want to use moly grease in a high speed roller bearing application because the grease is too slick which may cause the bearings to slide instead of roll.
