Different types of greases are typically formulated with three grease components: base oil, thickener and additives. The base oil lubricates, reducing friction between moving surfaces; this is exactly the same role that the base oil plays in a lubricant oil.

Grease characteristics according to thickener type CLICK to enlarge image 3.2.3. Intended use area division. Universal (general purpose) greases; Special greases with added solid lubricants, such as graphite, or molybenum disulfide (MoS 2). Usually used for high load and pressure bearing greases.
Grease with graphite has graphite particles to absorb and dissipate heat. Grease with only deoxidizer provides the best lubrication and is for use on clean surfaces. Grease lubricates most efficiently within the listed temperature range. Melting temperature is the point at which grease will fail and run out of equipment, leaving it to run dry.
Grease with calcium sulfonate thickener has good heat resistance and excellent moisture and oxidation resistance. Grease with moly (molybdenum disulfide) and grease with graphite have excellent resistance to wear and can withstand high-load and high-pressure applications. Grease with zinc neutralizes acid and is a good replacement for leaded ...
Nye's mission is to partner with innovative companies to develop high-performance solutions using our lubricant technology and engineering expertise.
The synthetic base of this grease helps it to last longer than non-synthetic greases could, which results in fewer and less frequent re-applications of lubricant. The graphite in this grease helps it to withstand high temperatures and high pressures, and because SGL #5 does not employ a clay based thickener, "bake out" and "carbonization ...

Chevron Open Gear Grease is formulated with high viscosity mineral oils in a nonsoap-based thickener. This grease appears brownish-black and is extremely tacky. Chevron Open Gear Grease contains special functional fillers (molybdenum disulfide and graphite), …
Graphite grease is intended for lubrication of hard heavy-loaded mechanisms (open gearboxes, screw joints, guide screws, jacks, springs, etc.). Lubricant is efficient at the temperatures lower than minus 20°С in springs and other similar mechanisms.
How does a grease thickener work? ... What colour is graphite type solid lubricant? Grey-black. Which solid lubricant has the greater load-carrying capacity, graphite or Teflon? Graphite (50,000 psi) Which lubricant may be used where oil and grease are not adequate? Solid lubricants.
A lubricant composition comprising water, graphite, an organic thickener, sodium molybdate, and sodium pentaborate. Other additives are sodium bicarbonate, ethylene glycol, or mica. The composition is effective in the hot forging of metals, is virtually non-flammable, and generates very little atmospheric pollution during use.
Thickeners hold the oil in place, much like a sponge holds water. When mated parts move, the thickener is sheared and releases oil to form a lubricating film between moving parts. Thickeners reabsorb oil when motion stops. Solid Lubricants like PTFE, MoS 2, and graphite are load carrying additives that improve the lubricity of a grease,
Molykote Longterm 2 Plus Extreme Pressure Bearing Grease is used successfully for bearings, spline profiles and clutches in highly stressed motor vehicles, tractors, cranes, earth-moving machines, conveyor belts and forklift trucks. Also suitable for yaw and pitch bearings including those in …
The thickener in a lubricating grease is the component that sets grease apart from fluid lubricants. Thickeners are molecules, polymers, or particles that are partially soluble in lubricating fluid; they arrange themselves in such a way that they impart a semi-solid consistency to the grease.
HUSKEY OPEN GEAR GREASE is a heavy-duty, highly tenacious, semi-synthetic open gear lubricant containing a balanced blend of molybdenum disulfide (moly) and graphite, incorporated in a non-asphaltic, non-melt base grease that contains no clay fillers. Treated with the most modern additives to provide lasting protection against extreme pressure ...
There are many criteria to consider when selecting a high-temperature grease for hot, grease-lubricated equipment. The selection must include consideration of oil type and viscosity, oil viscosity index, thickener type, stability of the composition formed by the oil and the thickener), additive ...
Grease is a thick and oily substance usually used as a lubricant. As a true sample of grease, it must contain either oil and/or other lubricants usually mixed using a thickener, usually a soap so as to form a solid or semisolid substance. Greases come in different types depending on the ...
Graphite Grease. It is highly refined mineral oil based grease with complex aluminum thickener and with a high concentration of solid lubricants additives which together with chemical type additives provide optimum lubricating characteristics like. Low friction coefficient; Stability under the highest stresses; Free of lead, heavy metals
Thickener – The most common thickeners used for greases are soaps. The soap can lend important properties to the grease, such as water resistance, chemical stability, and an improved viscosity index. Some common thickeners used include lithium, clay, and silica soaps.
Two high temperature lubricants adapted to be applied by an airless spray system are disclosed. The first is designed for use at temperatures of between 200 to 315°C and comprises a combination of water, graphite, montmorillonite, xanthan gum, surfactant/defoamer and a preservative. The second is designed for use of temperatures between 425 and 540°C and includes any combination of water ...
Grease is a semisolid lubricant.Grease generally consists of a soap emulsified with mineral or vegetable oil. The characteristic feature of greases is that they possess a high initial viscosity, which upon the application of shear, drops to give the effect of an oil-lubricated bearing of approximately the same viscosity as the base oil used in the grease.
LUBRICANTS FOR A WIDE RANGE OF APPLICATIONS. Molykote™ is the brand name for the specialty lubricants from DuPont. The Molykote™ brand is designed and engineered to solve your difficult lubrication related problems and save energy by reducing friction and wear.
National Lithium Complex Grease is manufactured from refined, high viscosity index base oils & a lithium complex thickener. This grease is fortified with EP additives, rust and oxidation inhibitors especially developed for bearings operating at high temperatures and under severe and shock loads. ... National Graphite Grease is a calcium based ...
Grease is another type of lubricant, and it typically consists of oil that has been mixed with a thickening soap. This makes it more adherent than oil alone and ideal for preventing corrosion. Lubricants and grease range in consistence from water-like to nearly-solid.

However, some greases are fortified with solid film lubricants such as Graphite or Molybdenum Disulphide (sometimes referred to as Moly) . These solid film lubricants give no real benefit in rolling element bearings but are particularly suited to heavily loaded, sliding applications such as splines, landing gear bogie pivot pins and the like.
Sep 15, 2016· Greases are made by using oil (typically mineral oil) and mixing it with thickeners (such as lithium-based soaps). They may also contain additional lubricating particles, such as graphite, molybdenum disulfide, or polytetrafluoroethylene (PTFE, aka teflon).
