All You Need To Know About Liquid Grease

If you are talking about liquid grease, it only creates a slight recoil. Because we usually hear about oil grease rather than liquid. However, the spray used on mechanical/metal and plastic items is handy.

Liquid grease is the most practical solution, particularly for reducing friction & abrasion, corrosion, and increasing the life of parts/components. So what exactly is liquid grease? What are its characteristics? Let’s discuss the following:

What is Liquid Grease?

When you think about grease, solid oil must come to your mind. Nevertheless, liquid grease is actively used for many practical purposes. To keep your machinery, cars, mechanical equipment, and tools lubricated thus, you can use grease

at all times, even in all conditions. Basically, this liquid grease is used to protect against water ingress. Besides this, it can save your machines and components from rust and corrosion. It also reduces friction in contact with their equipment and appliances. The liquid spray contains pretty high viscosity. You can use this grease on many machines. But it is usually suitable for the automotive industry, like wheel bearings, chassis, and gears.

Uses Of Liquid Grease

Uses Of Liquid Grease:

Liquid grease is used in short cases as follows;

  • Equipment or their components which have not been used for a long time,
  • Occasionally used tools or their elements,
  • Equipment or their elements that are not readily available for lubrication,
  • Worn machine or mechanical equipment.
  • Automobiles or their components operate at high pressure or heat,
  • Cars or elements operate under overload conditions.

How To Choose Your Liquid Greases For Bearing

When you are going to buy liquid grease for bearings, you should follow the below points. Some features require your fluid grease tick for the bearing before purchase. Let’s take a look at them:


Product quality should be good. It should be durable and have a life of more than one year. The best way to check the quality is to review other consumers who have used the product.


Price is a crucial factor when purchasing any product offline or online. It would help if you calculated how much you will spend on the product.

And compare it with other sellers offering the same product at different prices. If the price difference is too much, go for the higher-priced ones. They will be better in quality and durability than lowered-priced ones.


Before buying, make sure that your desired product’s features are present in that particular model! You can read reviews about each feature from other customers who have used these features. After reading them, you can decide if these features suit your needs!

What Are The Features Of Liquid Grease?

Its most crucial characteristic is relatively high viscosity. Liquid grease features include;

  • Generally, it has exceptional lubrication function and protection for moving machines or their parts.
  • It can be used on all hardware, components, and cars, including heavy construction machines.
  • It is very good at resisting corrosion and has outstanding adhesion.
  • Also, it is quite resistant to high pressure.
  • Hence, it repels water and decreases corrosion.
  • Provides good cleaning
  • Therefore, it increases the tool’s life and doesn’t damage the paint.

Liquid Grease Spray

The liquid grease spray is ideal for metal-to-metal applications. It’s because they need heavy-duty lubrication and security from rust and corrosion. So, it’s safe from 0 F to 300 F for unbeatable protection. As you know

Grease is an aerosol-based lubricant that provides adequate performance under high friction loads. Manufactured under state-of-the-art auto machinery, high viscosity, multi-utility heavy friction spray fluid.

It’s used for lubricating moving parts, sealing moisture to protect against rust and corrosion, and prolonging communal life. Excellent work properties cover the panels and leave a thin coat layer after application.

Can I Use Liquid Grease For the Gearbox?

ISO VG 220 oil is the manufacturer’s recommended product for the gearbox. Nevertheless, the user is mixing ISO VG 220 gear oil with an NLGI #2 grease due to severe wear on gear teeth. As a result, using this mixture solved the problem to some extent.

But the question is can I use liquid grease for the gearbox? Generally, semi-liquid lubricants such as NLGI #000 or #00 are recommended for small gearboxes that fail frequently. This technique simplifies maintenance practices by reducing the likelihood of a leak and the need to top up components.

Another application of semi-liquid greases is in heavily loaded open gears. In this case, you can lose your money using this grease. In this case, open gear grease or oil is best.

But, grease can be effective for a short period, as the lubricant stays in place due to the stickiness of the oils and concentrates and then falls off. Resulting in removing pollutants from the environment.

Liquid grease is best for oil-lubricated gearboxes to decrease lubricant leakage or noise. It is just a matter of pros and cons analysis.

The best advice for you is to use a tiny grease so it won’t significantly affect operating parameters. But it can help control undesirable factors.

FAQ (Frequently Asked Questions)

Q. Is grease a liquid lubricant?

Grease is solid to a semi-liquid product made of a liquid lubricant and a thickening agent. The type of concentration and the liquid lubricant’s properties determine a grease’s primary characteristics. The oil acts as a lubricant while the thickener holds the oil and resists flow.

Q. What is the difference between oil and Liquid grease?

Liquid grease is usually thickened oil. Liquid greases are generally solid at room temperature, while oils are typically fluid. All oil can be turned into grease, but not all grease comes from oil.

Greases are generally only used in machinery, tools, or equipment, while oils have other non-industrial uses.

Final Word:

In summary, liquid greases come from base oil combinations, selected additives, and a thickener like other greases. Typical applications for liquid greases are the lubrication of open or closed gears.

Also, you can use this liquid grease for the central lubrication system for commercial vehicles. Even so, you can use it in gear units unsuitable for splash lubrication with oil. Finally, We can say that, With this liquid grease, you can lubricate your closed plain bearings and roller bearings.
