For instance, a fluorinated hydrocarbon-based (type of synthetic oil) grease may work effectively as high as 570ºF (300ºC) in space applications but may also cost hundreds of dollars per pound. For these nonmelting products, the lubricating oil burns off at high temperatures, leaving behind hydrocarbon and thickener residues. Browse our latest Greases offers. $15.09 $ 15. This grease is ideal for use where temperature, water washout and contamination, extreme loads or a combination of these factors are present. Some clay-thickened (bentonite) greases may similarly have very high melting points, with dropping points noted on the product data sheets as 500ºC or greater. KILN GREASE HT's base fluid is combined with an aluminum complex thickener which produces a grease with exceptional high temperature, water resistance and high load characteristics. They typically consist of thickener systems with high drop point, synthetic base oils and selected additives.ADDINOL offers products with upper operating temperatures between 180 °C and 285 °C (depending on the specific product) for high-temperature applications. High-temperature, Poly Urea based grease for rolling and sliding bearings at normal to medium peripheral speeds and high operating temperatures. Operating temperature: -25 °C - 150 °C... Relubrication with a grease gun on to the grease nipples or with an automatic lubrication system. The operating temperature may be less than what it seems. The grease manufacturer will select materials given their familiarity, and perhaps availability, of the raw materials. Compatibility, or incompatibility, between high-temperature greases must be addressed prior to selection. While the thickener has a high dropping point, the composition begins to thermally degrade at temperatures which limit its usefulness over time at high temperatures. Instead, ASTM D2265, which supports a more expansive temperature range and includes higher temperatures, is heavily utilized. The Group II and Group III are mineral oils that experience extensive processing to remove the reactive molecules and saturate (with hydrogen) the molecules to improve stability. When selecting lubricants for oil-lubricated applications, one often begins with the consideration of base oil performance properties. Even though the fluid may be capable of resisting thermal breakdown from the heat of the drying system, the moisture poses a performance risk that may not be entirely eliminated. The exception is the calcium sulfonate complex thickener system. The break point at which the individual oil molecules in a highly refined (Group II+, Group III) mineral oil and synthetic hydrocarbons will begin to unravel, releasing carbon atoms from the molecular chain, is about 536ºF to 608ºF (280ºC to 320ºC). High Temperature Lubrication. p. 53. Although the polar products are reactive, they help to dissolve or disperse additives to produce the final product. DSF-5000 ® is a “Technically Advanced” synthetic grease designed for use on equipment where constant operating temperatures can reach 1500° F / 815° C, and even higher intermittently. The test is undertaken at a pre-determined speed and temperature. Following the Arrhenius rate rule, chemical reactivity doubles for each 10ºC rise in temperatures, incompatibility issues are more pronounced at elevated temperatures. An extreme-pressure additive provides exceptional protection against wear and shock loads, while additional additives enhance resistance to high-temperature oxidation and protection against rust. Synthetic esters and PAO (synthetic hydrocarbons) are next, followed by silicones and a few other exotic synthetic oils. The oxidative and thermal properties can be very good as a consequence of the removal of the reactive heterocyclic molecules. Free Next Day Delivery available. Multiuse greases are required in a variety of different applications, many having different performance challenges. Consider whether the application is intermittent or continuous high-temperature.

Do heating and cooling cycles accompany machinery operating and nonoperating intervals? The thickeners, additives and base oils may each have problems at differing temperature ranges and time limits in use. Similar to the polyurea, it possesses inherent antioxidant, rust-inhibiting properties, but in addition has inherent high dropping points and EP/antiwear properties. Additionally, there are polar products that remain in the Group I base oils called heterocycles (nitrogen, sulfur and oxygen- containing molecules). Get … In addition to heat resistance, the grease to be used in a hot steel mill application may require exceptional load-carrying capability, oxidation stability, mechanical stability, water wash resistance and good pumpability, and at a price suitable for large-volume consumption. OKS 420 is a high-temperature grease for universal use at increased requirements. L-80 is applicable to the majority of situations specifying grease lubrication, especially in high pressure, water and salt water conditions including wire ropes. The additive must be capable of working synergistically with the thickener and the oil to lead to a balanced, stable mixture of the three distinct components. ASTM D566 is currently obsolete and does not support the high temperature range of popular high temperature greases, such as complex soaps, polyurea, and calcium sulfonate grease. Read about company. 6 However, unless the grease composition is properly fortified against oxidation and thermal degradation, the end product showing a dropping point of 500ºF (260ºC) or greater would not be any more useful for long-term service than a grease with a low dropping point. Does it exceed 392ºF (200ºC)? Use a contact or noncontact sensor to measure the operating temperature of the grease. Product Name & Description Specifications; RENOGEL BHT NLGI 2, 3: High temperature bentonite clay grease. Polyurea thickeners might become more popular but they are difficult to manufacture, requiring the handling of several toxic materials. However, it does not have the pro-oxidant tendencies of the metal soap-thickened greases. This is similar to what is to be expected with most industrial oil-lubricated applications. With the variety of details to resolve, the selection of greases that must accommodate extreme temperature conditions poses some of the more challenging lubrication engineering decisions. Because greases represent a complex mixture of chemicals with a well-defined and engineered balance, the addition of unplanned chemicals tends to upset the balance and degrade performance levels. (1994). Follow these steps when selecting a high-temperature grease: Determine the real temperature range. The additives tend to provide properties for greases in fashion similar to lubricating oils: oxidation stability, corrosion resistance, wear resistance, low temperature flow characteristics, water resistance, etc. Because oils, additives and bases will react at various rates, there is something good to be said about using simpler products. It is an NLGI 2 grade and is manufactured with a proprietary, high-temperature lithium complex thickener system. Grease is composed of three components: the base oil, the thickener and the additive package. There is general correlation between a grease’s useful temperature range and the expected price per pound. 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 composition and properties, ambient temperature, operating temperature, atmospheric contamination, loading, speed, relubrication intervals, etc. The grease’s long-term behavior is influenced by the causes of degradation, three of which are particularly important: mechanical (shear and stress) stability, oxidative stability and thermal stability.
