What exactly is Molybdenum Lubricant?

Molybdenum a mineral found in nature has been used to enhance the lubricity for mechanical parts over many centuries. It acts as an antiwear layer by drawing itself onto the metal surface. If the additive cannot dissolve in oil, it will be ineffective. You will need a suitable oil lubricant in order to prevent it from clogging filters and passageways.

Molly grease may be found in nearly every part of heavy-duty vehicles. To prevent internal gearing from bind, U-joint manufacturers specify that grease should contain no more than 5% of molybdenum sulfide. Moly grease used on slack adjustment may reduce the equipment’s performance.

Molybdenum grease lubricant has low friction but high pressure-absorption. It has stick-slip protection and anti-corrosion. Moly grease can be used to press-fit all types of machine components. Moly grease can also be used to prevent gear pitting. This grease can be used to lubricate metal-to–metal contacts and machine parts. It is also useful for the lubrication of threaded and roller bearings.

Molybdenum sulfide also makes a great lubricant. It’s a mixture of molybdenum, sulfur atoms. Through its sulfur atoms, this compound can bind to metal surfaces. Therefore, it prevents any asperities from touching the metal surfaces. MoS2 is another common molybdenum lubricant. It has particles sizes that range from 1 to 100 um. The sliding friction properties of MoS2 are low at 0.01 to 0.01 s.
