The lubricant choice for a specific application is determined by matching the machinery design and operating conditions with desired lubricant characteristics. Because of its consistency, grease acts as a sealant to prevent lubricant leakage and also to prevent entrance of corrosive contaminants and foreign materials. Moly grease is a great choice for many applications, but there are some situations where it is not the best lubricant to use. Emergency running properties, i.e. Moly grease can also be used as a gun lubricant. Warranty, View The mineral oil in grease can flash, burn or evaporate at temperatures greater than 177C (350F). Well also discuss what the best moly grease for heavy equipment is. Using it in its pure powder form would be prohibitively costly in the majority of applications. Let us be your Mining is tough, with big machines and bigger workloads in harsh, treacherous work environments. Metallic soap is the most often utilized thickening by grease makers. How Shell is Preparing for a Cleaner-Energy Future, Shell Premier Heavy Duty Installer Program, NLGI High-Performance Multiuse Grease Specifications, Importance of Regular Maintenance to Maximize Efficiency and Minimize Downtime, Understanding Coolant Types is Important to Your Engine and Cooling System, Heavy Duty Engine Oil (HDEO) Frequently Asked Questions, Pickup & Passenger Vehicle Diesel Engine Oil FAQs, Real World Testing for Heavy Duty Engine Oil (HDEO), View As grease temperature increases, penetration increases until the grease liquefies and the desired consistency is lost. Moly grease can start to break down at temperatures above 200F. Complex greases are made by combining the conventional metallic soap with a complexing agent. Other ingredients imparting special properties may be included" (ASTM D 288, Standard Definitions of Terms Relating to Petroleum). To address this serious issue, the commercial bakery decided to conduct a test on moly grease in wheel bearings. Fuel Additives Make sure to consult your owners manual before applying this lubricant anywhere else. The consent submitted will only be used for data processing originating from this website. Additives can play several roles in a lubricating grease. With automatic lubrication, there may not be the same need for Moly because every bearing will receive the grease it requires to keep it lubricated and purged of contaminants. Thanks for reading! It is recovered from the rocks and then purified for direct use in lubrication. 1. Having stated so, the only plausible conclusion for those years was that the substance was molybdenum disulfide. MasterPro offers a complete line of automotive fluids, greases, and aerosol products for most aftermarket car care needs. Hydraulic Oil Automatic lubrication solves the problem of inconsistent lubrication by reducing the human element. Moly grease is not recommended for use in sealed bearings. Most popular lubricants will eventually degrade and burst at excessive pressure or increased temperatures, resulting in wasteful wear and perhaps catastrophic failure. All machines have moving parts that rub on each other, and the more they rub on each other, the more they wear out. Greases containing moly are recommended for roller bearings subjected to very heavy loads and shock loading, especially in slow or oscillating motion such as found in universal joints and CV joints. Mobilux EP 2 Moly is a premium quality multi-purpose, lithium-base NLGI No 2 grease recommended for general industrial applications. We use them in everything we have--tractors, trucks, cars and especially my Monster Truck, The EQUALIZER. ATV & UTV You only need to take note of the difference. This substance helps to reduce friction and wear on metal parts. Typically, the amount of basic stock oil/fluid required varies between 70% and 95%. Snowmobile History. Can You Use Moly Grease As A Chain Lubricant? Grease compatibility is an issue because of what can happen when two incompatible greases are introduced to each other. It contains an extreme-pressure additive for increased load-carrying ability. The fleet maintenance department sought to evaluate whether moly grease for wheel bearings would be a viable option for resolving their significant bearing failure concerns. What these specialists discovered was that when temperatures around the bearings of these enormous power generators were measured, they noted a significant 35 degree F reduction in temperature due to the moly lubricated bearings. A good example of how well the Oil Stabilizer works is when I ran it in my EQUALIZER motor that had NO oil pressure. Mobilux EP 2 Moly is a premium quality multi-purpose, lithium-base NLGI No 2 grease recommended for general industrial applications. A soap/water lather may suspend the oil in the grease, forming an emulsion that can wash away or, to a lesser extent, reduce lubricity by diluting and changing grease consistency and texture. They are both forms of carbon that have different structures. Take note that regardless of how hard you push down on your cards, they will not compress farther than a specific point. loyalty program These greases have a tendency to overwhelm the match-honed pistons and cylinders that we use inside of our pumps and valves, which can cause them to seize over time. Lucas Marine Grease is a premium, extreme pressure, multi-purpose, heavy duty OBCS grease containing unique polymers, anti-wear agents and tackifiers with inherent rust and oxidation resistance to provide the highest performance properties. It provides hardworking protection at a lower viscosity than CK-4 oils. Dropping point is an indicator of the heat resistance of grease. For example, if you work in a high-pressure environment, more of your lubrication needs would be met with a heavy-duty grease. Because grease remains in place, a lubricating film can instantly form. Compatibility With Specific Surfaces. For more information, contact your local ExxonMobil contact or visit www.exxonmobil.com Find an Automotive Service Professional As far back as 1764, historical documents indicate a weird gray-colored mineral material that was employed and rubbed into presses and a variety of equipment during that time period. Lubrication grease is a mixture of oil and soap or another thickener. The next element is a thickener, which should be used in amounts ranging from 3% to 30%. Marine Outboard A grease's consistency is its resistance to deformation by an applied force. A lubricants purpose is to keep these two metal surfaces apart. {"links":[{"url":"https://www.graco.com/us/en/vehicle-service/solutions/articles/choosing-the-right-grease-for-fleet-truck-chassis-and-components.html", "anchor_text":"Choosing The Right Grease For Fleet Truck Chassis And Components"},{"url":"https://www.graco.com/us/en/vehicle-service/solutions/articles/grease-guns-get-in-the-way-of-improving-productivity.html", "anchor_text":"Dont Let Grease Guns Get In the Way of Improving Your Productivity"},{"url":"https://www.graco.com/us/en/vehicle-service/solutions/articles/auto-greaser-keeps-farm-skid-steer-loader-in-service.html", "anchor_text":"AUTO GREASER KEEPS FARM SKID STEER LOADER IN SERVICE"}]}, Component Parts Not Manufactured by Graco. The tests were designed to put the grease through its paces in terms of wear, torque, and bearing conditions. Moly grease is usually in a solid form. This is why it lasts very long on metals. In this case, moly grease for ball joints was the way to go. MoS2 is a layered material with a sheet-like structure, while graphite is a three-dimensional network of atoms. I use the diesel fuel treatment in my big rig that hauls the Monster Truck. 1. Although both types of grease are resistant to water, lithium grease offers a higher level of water resistance than moly grease. This is the ability of a grease to resist a chemical union with oxygen. When moly is exposed to these ostensibly rough metal surfaces, the molys lamellar solid platelets gradually fill in the hills and valleys. ExxonMobil is comprised of numerous affiliates and subsidiaries, many with names that include Esso, Mobil, or ExxonMobil. And they could lose their viscosity and offer poor lubrication. Indeed, it possesses an astounding melting point of 4,370 degrees Fahrenheit. Others say that the Moly actually coats abrasive contaminants to prevent them from scoring the moving surfaces inside of the bearing. Shell Rotella T4 Triple Protection, View This gray-colored mineral was meticulously rubbed into metal surfaces and then polished to a high gloss, earning it the moniker burnished black.. Fluid level does not have to be controlled and monitored. Nonsoap thickeners are also gaining popularity in special applications such as high-temperature environments. Lithium is multipurpose and can be applied to different areas. AP Grease is a lithium based multifunctional high temperature, water resistant grease. If you have a machine that is running two types of . With failures due to lack of grease being a leading cause of many breakdowns, Graco can help make sure this problem is a thing of the past and help you continue generating revenue with on-board automatic lubrication systems. 38 semi-trucks, police vehicles, and municipal buses were lubricated with a lithium grease containing 3% moly during a two-year period. Moly grease has a film-forming structure. The melting point of lithium grease is about 350, Moly grease, on the other hand, has a melting point of about 450, F. Some experts have pointed out that the advantage that moly grease has over lithium is theoretical. You are pressed to keep it on the road while at the same time managing your overall costs. in the case of mixed friction providing of wear protection by solid Lubricants and EP additives, Good protection against scarring (false Brinelling), Good protection against fretting corrosion. Disadvantages of Moly disulfide grease. If you need a grease that can withstand high temperatures, look for a product that is specifically designed for high-temperature applications. The NLGI has established consistency numbers or grade numbers, ranging from 000 to 6, corresponding to specified ranges of penetration numbers. Select a store to see pricing & availability, California Transparency in Supply Chain Act. The last component to consider in terms of the chemicals used to manufacture grease is the additives. Mineral oil-based fluid lubricants (oil and grease materials) function properly where the designed surface areas and shaft speeds allow for the effective formation of an oil film, as long as the machine operating temperature envelope falls between -20C and 100C (-4F to 212F). One situation where moly grease is not the best choice is when you need a high-temperature lubricant. This additive opened the possibility for sealed bearings that didn't need re-lubrication, because even when the oil seeped out, the molybdenum disulfide would act as dry lubricant. Penetration depends on whether the consistency has been altered by handling or working. Ultimately, Graco does not make recommendations for the grease used in a given application because choosing the right grease is really up to the equipment manufacturer and the customer. If the temperature of a grease is lowered enough, it will become so viscous that it can be classified as a hard grease. Also, where relubrication is infrequent, molybdenum disulfide provides extended lubrication protection. Health and Safety recommendations for this product can be found on the Material Safety Data Sheet (MSDS) @, http://www.msds.exxonmobil.com/psims/psims.aspx. Typically, greases with molybdenum disulfide in them are better suited for places with lots of dirt and dust. This is the only grease I've ever used that actually does what it says it will do. Moly grease is best for situations where the heat and pressure are high and metals rub over each other.
