Molybdenum Disulphide and Lithium Grease – Difference, Properties, Characteristics and Importance

admin / October 29, 2021

It’s difficult to picture a machine running without grease. Any dynamic machine process relies on bearings, which require grease to keep them lubricated. The most common universal greases were crude limes with vegetable oils. However, machine design has made significant progress in the last few decades. As a result, operating parameters have changed, along with that the demands for lubricating greases have also changed. As a result, a huge number of lubricating greases are developed, resulting in wide arrays of greases on the market.

The most common grease that is used in every industry is Lithium and Molybdenum containing greases. They both have different properties, purposes, and features but both are equally important. –

  • Lithium Grease is used in household appliances like drawers, hinges, etc. it is made of lithium soap which is a non-detergent soap that contains stable and non-corrosive properties.
  • Some manufactures use Molybdenum grease to protect metals. This grease is used for extreme pressure protection and prevents wear and tear of brake wheel bearings.

Many companies provide both greases, but Bisley International is one of the reliable Lithium and molybdenum disulphide grease suppliers in the US. Their office is located in Houston Texas and they serve most multinational, big, and small companies all over North America. They are in this business for 65 years delivering various resources to different industries, but they have served 30 years in the grease industry.

Molybdenum Disulphide

The molybdenum disulphide (MoS2) is the most natural variation of metallic elements. It is recovered from the rocks and then purified for direct use in lubrication. Because the metallic element disulphide is made up of energy, it has the strength to withstand heat and pressure. This is especially true if small amounts of sulphur are available to react with iron and provide a chemical compound layer that is compatible with MoS2 to maintain the lubricating film.

Properties of Moly Grease

  • Suitable lubricant for high-load and high-stress applications.
  • solid lubricant
  • High operating pressure can be tolerated
  • High operational temperature tolerance
  • Anti-seize characteristics

Lithium Grease

Lithium-based greases are the most common greases in the world, with a market share of over 75%. Even though several types of greases may be required in a very specific plant, there have always been efforts to reduce the number of greases required, from a purchasing and availability standpoint. This is why lithium grease, multi-purpose grease, was introduced.

Properties of Lithium Grease

  • Good stability
  • High-temperature characteristics
  • Water-resistance properties
  • Can improve extreme pressure, anti-wear, rust, and corrosion feature with additives.

Lubricating grease is an inspiring product made out of mineral or vegetable oil blended with soap as the main ingredients. The oil is combined with the soap and churned into an emulsion, resulting in semi-solid grease. All types of grease are used for different purposes. This is the reason why the grease industry is so vast. Multipurpose grease solves most of the problems, but not all of them.

If you’re buying grease for your machinery, check the brand and characteristics like viscosity, abase oil, additives, and consistency to know if the product is right for your machine. Any wrong or impure product can damage the machine and its bearing thereby reducing its performance.
