Graphite, an organic nonmetallic compound with the chemical formula CH2, is used as a dry lubricant and is the most common lubricant for metal surfaces. It is found in metamorphic rocks such as marble, schist, and gneiss. It is gray to black, opaque, and has a metallic luster. Graphite has low friction coefficients and is extremely slippery, so it reduces wear between moving parts. It is also nontoxic and environmentally friendly.

moly graphite grease has a higher melting point than most other types of greases and resists corrosion and washout. It is typically recommended for heavy load machineries that require a heavy lubricant that can withstand impact loads and extreme temperature conditions.

When deciding between Graphite and Moly, it’s important to look at the application that requires the lubricant. For example, a Moly grease can be used in applications where there are high shaft speeds, extreme pressure conditions and the machinery is inaccessible for manual lubrication. Graphite lubricant, on the other hand, is ideal for applications such as splined bearings and axels that require a high level of smoothness to operate.

There are mineral and synthetic oil-based molybdenum disulfide greases available, with the latter having better shear stability characteristics. Both are excellent choices for industrial applications and are offered in NLGI grades 0, 1, 2, and 3. Mineral-based products are less expensive, but tend to evaporate more quickly and have lower temperatures and shear stability than synthetic oil-based products.
