When Not To Use Moly Grease: How to Properly Lubricate[Do’s & Don’t]

When Not To Use Moly Grease. Moly grease is a great option for many applications, but there are also times when it’s not the best choice. 

Here are four situations where you should avoid using moly grease: 

1. When You Need High-Temperature Resistance

Moly grease has a lower melting point than other types of greases, so it isn’t ideal for high-temperature applications. If you need grease that can withstand higher temperatures, look for one that contains synthetic base oil. 

2. When You Need Chemical Resistance

Molybdenum disulfide, the main ingredient in moly grease, isn’t resistant to some chemicals. If you’re using your equipment in an environment where it will be exposed to harsh chemicals, opt for a different type of grease. 

3. When Water Washout is an Issue

Moly grease can wash out of bearings and other moving parts when exposed to water. This can lead to equipment failure and downtime. If you’re working in wet conditions, choose water-resistant grease instead.

4. When Cost is a Concern

While molybdenum disulfide is relatively inexpensive, adding it to lubricating oils can increase the cost of the final product significantly.

Moly grease is a great lubricant for many applications, but there are a few instances where it’s not the best choice. One example is when you’re working with stainless steel. Moly can cause staining and corrosion on stainless, so it’s best to avoid using it on this type of surface.

Another instance where you might want to steer clear of moly grease is if you’re going to be doing any high-temperature work.

Moly has a relatively low melting point, so it can start to break down at elevated temperatures. If you need a grease that can withstand high heat, look for one that’s specifically designed for that purpose.

Moly Grease Vs Red Grease

Molybdenum disulfide, or moly grease, is a lubricant that has been around for many years. It’s often used in high-temperature applications because it doesn’t break down at high temperatures like other lubricants. Moly grease is also waterproof and resists corrosion.

Red grease is a newer type of grease that contains molybdenum disulfide as well as other additives. These additives make red grease more resistant to extreme temperatures and pressures. Red grease is also less likely to leak than other types of grease.

Moly Grease Vs Lithium Grease

Moly Grease Vs Lithium Grease Moly grease and lithium grease are both types of lubricating grease. They are used for different purposes and have different properties.

Molybdenum disulfide (moly) is an inorganic compound that is often used as an additive to lubricating greases. It is a soft solid that has a Mohs hardness of 2-1/2 and is insoluble in water. When molybdenum disulfide is added to grease, it acts as an extreme pressure (EP) additive.

This means that it can protect metal surfaces from wear, galling, and seizure at high temperatures and pressures. Lithium soap-based greases are the most widely used type of grease. They are made by combining lithium hydroxide or lithium carbonate with mineral oil or synthetic oil.

The resulting product has good stability over a wide range of temperatures and does not break down easily at high temperatures. Lithium soap-based greases are also waterproof, which makes them ideal for use in wet environments or applications where frequent washdowns occur.

Best Moly Grease

It is difficult to choose the best moly grease because there are so many types and brands on the market. Molybdenum disulfide (moly) greases are made with a fine powder that is added to other lubricating oils.

This creates a thick, sticky substance that can provide excellent lubrication and protection against wear, even in high-temperature or heavy-load applications.

Moly greases typically have a base oil viscosity of ISO 220 or higher. The moly content can range from 2% to 25%. The higher the moly content, the greater the load-carrying capacity and resistance to extreme pressures.

However, too much moly can make the grease difficult to pump and can cause premature bearing failure. For this reason, it is important to select a grease with the appropriate moly concentration for your application.

Moly greases are often used in automotive and industrial applications where loads are heavy and temperatures are high.

They are also commonly used in off-road vehicles, construction equipment, and agricultural machinery. Many moly greases are NLGI grade 2 or 3, making them suitable for centralized lubrication systems.

Moly Grease Uses

Moly grease is a type of lubricant that contains molybdenum disulfide, which is a solid lubricant. Moly grease can be used in a variety of applications where regular greases would not work as well.

For example, moly grease can be used on high-speed bearings, gears, and other moving parts that are subject to heavy loads or vibration.

Moly Ep Grease

Moly EP Grease is a multipurpose, extreme-pressure grease that can be used in a variety of applications.

It is made with a blend of molybdenum disulfide and other solid lubricants that provide long-lasting protection against wear, rust, and corrosion. This grease also has excellent water resistance and will not break down in high temperatures.

High Moly Grease

Molybdenum is a chemical element with the symbol Mo and atomic number 42. The name is derived from the Ancient Greek μόλυβος molybdous, meaning lead, since its ores were confused with lead ores.

Molybdenum minerals have been known throughout history but the element was discovered (independently) in 1778 by Carl Wilhelm Scheele and again in 1781 by Peter Jacob Hjelm.

Molybdenum does not occur naturally as a free metal on Earth; it is found only in various oxidation states in minerals. The free element, produced by reductive smelting, is a hard, silver-gray metal with a Mohs hardness of 5.5 and a standard atomic weight of 95.95 g/mol.

In nature, molybdenum exists as an oxide or sulfide; about two-thirds of world production comes from the latter process.

[2] While molybdenum is an essential trace nutrient for some bacteria and fungi,[3] animals cannot metabolize it because they lack enzymes to break down or utilize molybdates.[4][5][6]

Molybdenum enzymes catalyze important biochemical reactions including denitrification (reduction of nitrates), nitrogen fixation (conversion of N2 into ammonia), sulfur metabolism[7], and hydrogenase activity.[8][9][10]

Molybdate reagents are also used to detect lactic acid.[11] Most industrial uses for molybdenum involve its alloying with iron, steel, aluminum, magnesium, etc.; this use accounts for approximately 80%[12] of global consumption.

Smaller amounts are consumed as oxides or compounds to add luster and durability to paints and pigments; these uses account for about 8% of global consumption.

High moly greases are designed for applications that require high load-carrying capacity combined with good resistance to wear and extreme pressure properties. These greases typically contain between 2% and 5% molybdenum disulfide (MoS2).

You’ll often see them referred to as “high performance” greases or “extreme pressure” greases due to their ability to withstand heavy loads without breaking down. One common application for high moly grease is construction equipment bearings subject to shock loading from dirt, debris & rocks.

Another application would be off-road vehicles that encounter similar conditions while driving over rugged terrain.

The main advantage of using high moly grease is extended bearing life due to the added protection against wear & tear provided by the MoS2 particles suspended within the grease matrix.

Do I need to use Moly Grease with my automatic lubrication system?

Automatic lubricants, such as Moly Grease by Pennco, are designed to be used when certain lubricants are required for a specific application.

If you’re not sure whether or not your application requires the use of Moly grease, then it’s advisable that you stay with your conventional lubricant.

Conventional lubricants can provide sufficient lubrication in most applications. When you use conventional lubricants to lubricate your bearings, valves, and other moving parts, you should expect them to work just fine.

When your automatic lubrication system is working properly and you’ve added the appropriate amount of conventional moly grease to your system, then it will end up providing the necessary protection to the working parts that are being lubricated by your automatic lubricant.

Is Moly grease a solid or a liquid?

Moly grease is solid. Moly grease is solid when it’s in the container, and it’s a liquid when it contacts any of your moving parts.

You could mix Moly Grease with conventional lubricants and push it through an automatic lubrication system. However, mixing moly grease with conventional lubricant may cause the conventional lubricant to break down prematurely, thereby possibly leaving your automatic lubrication system less effective than it originally was.

You can continue to use your conventional lubricants if you choose, but it’s always a good idea to call Pennco if you’re not sure which way is best.

Moly grease is different from conventional lubricants. The way that moly grease works allow it to move in between the moving parts and stay in contact with them for extended periods of time. Conventional lubricants aren’t capable of doing this, and that’s why moly grease is necessary for many situations.

Is Moly grease good for wheel bearings?

Yes, moly grease is good for wheel bearings. Moly grease was originally designed with the purpose of lubricating ball bearings and roller bearings.

It’s important to note that moly grease can also be used in other applications, such as automotive and marine applications. You should always consult with your Pennco automatic lubrication system expert if you’re not sure which type of application is most appropriate for your moving parts.

There’s no reason that moly grease can’t work as a wheel-bearing grease. Moly grease is actually more effective than traditional wheel bearing grease because it moves over the surface of the wheel and maintains better contact with the wheel for longer periods of time.

Can you use Moly grease on brass?

You can definitely use moly grease on brass. Brass is an alloy of copper and zinc, and moly grease has a long history of being used to lubricate alloy bearings, particularly when they’re made of brass.
