What Is Lithium EP2 Grease? - Application Made Simple

How You Should Be Using Lithium EP2 Grease?

What Is Lithium Grease?

Understanding the technical jargon behind industrial solutions can be tricky. It can mean you won't get the most out of your application, or even use the wrong product altogether! Lithium EP2 grease is a high-quality multi-purpose grease used in applications throughout industry environments, but could you be using it incorrectly?

Every grease has three main parts - oil, thickener, and additives. To put it simply, the oil is responsible for lubricating components, the thickener determines the individual properties of the solution, and additives enhance the performance of the grease.

Lithium is the thickener for EP2 grease and is one of the most popular options for users and manufacturers alike. Each thickener offers different pros and cons, and lithium has brilliant multi-functional properties. As a versatile grease, Lithium EP2 is relied upon for a huge range of applications.

So How Is Lithium EP2 Grease Different?

While Understanding Lithium Grease Is Key, There Are Other Terms To Keep In Mind

White lithium grease is already a go-to for high-load conditions, however, the "EP2" can offer even better performance. "EP" stands for "Extreme Pressure", and the acronym is used for lubricants subjected to high load conditions. As we said before, additives are used to improve performance, and EP2 grease is used extensively for applications that need a solution that can handle high amounts of pressure.

The number at the end of each grease description is another matter and refers to the hardness of the grease. Developed by the National Grease Lubricating Insitute (NLGI) this system makes finding the right consistency much easier. These numbers range from 000, which is used to describe a semi-fluid lubricant, to 6, which is essentially a solid form.

NLGI 2 is the most popular grade of grease on this spectrum and has a consistency similar to toothpaste. Firm enough to remain in place but still easy to work with and penetrate, grade 2 can be used for a variety of applications. However, there are instances where another grade would be the right option, so make sure you double-check the grade recommended in the user guide or manual provided by your manufacturer.

What Are The Properties Of EP2 Grease?

Lithium EP2 grease is the perfect example of an 'all-round' lubricant that has a variety of benefits to offer, including:

  • High Adhesion: Thanks to the firmer consistency, lithium EP2 grease offers fantastic metal adhesion. This saves time by cutting down on re-application and reduces downtime in the process.
  • High Corrosion Protection: As a non-corrosive grease, using lithium EP2 grease will not corrode any components it is applied to. It also works to prevent future corrosion, extending the life of your machinery.
  • Heavy Load Bearing: This heavy-duty grease is excellent for anti-friction and plain bearings subjected to high load conditions, and the extreme pressure additives mean lithium EP2 grease can handle demanding conditions


When Should You Use Lithium EP2 Grease?

Considering the versatility this solution has to offer, using lithium grease is a great choice for many applications. Often used throughout industry and the automotive sector, EP2 is best suited to anti-friction and plain bearings, door hinges, locks, gears, and more. This grease also offers high-temperature resistance and can withstand anything from -10° to 140°C.

When Shouldn't You Use Lithium EP2 Grease?

While lithium grease is noted as a multi-purpose solution, we always advise against using one product for everything. In particular, taking your environment into account is important. Lithium soap will emulsify when in contact with water, so, applications involving damp environments demand grease with better moisture resistance. Calcium Sulphonate is a high-pressure grease with very high water resistance, making it the perfect alternative.

Another issue for lithium grease is that while it can handle high temperatures, extreme temperatures are another matter. TG68504 is a grade 2 consistency lithium grease, which can withstand a wide temperature range from -50° to 220°C.

The oil type and additives are a key factor here rather than the thickener itself, both are lithium, which is why choosing the right product is vital.

If you're dealing with a specialised application, a technical grease with additives designed for your environment or equipment is always best, and if you're unsure our team is always on hand with advice and free audits to help you find the right product.
