Lubricants are called materials of a special variety used to reduce wear of various kinds of nodes during friction of their structural elements. Products of this type can differ primarily in consistency. The performance characteristics of such tools and the scope of their use depend on this parameter. Very often in industry, as well as in vehicle components, for example, NLGI 2 greases are used.

Classification and manufacturers

NLGI is an international grease classification system developed by the American non-profit organization National Lubricating Grease Institute. This corporation was created in the USA back in the 30s of the last century. At the moment, it includes many different kinds of research, training, service organizations.

NLGI 2 greases are being marketed today, including well-known companies. For example, if you wish, in our time you can purchase the following brand materials:

• Delo.
• Shell.

The first parameter operated by the National Lubricating Grease Institute is the consistency or density of greases. To test such materials in the laboratories of this corporation, the technique of working penetration is used. The density of the material is checked by the organization's specialists using a special type of device - a penetrometer with a cone. This device is lowered for 5 seconds into a grease heated to 25 ° C. Next, the immersion depth of the cone is measured.

Use area

Greases of NLGI classes from 000 to 6 can be sold on the market today. The most liquid materials of this variety are used in systems with a small cross-section of supply channels. Solid lubricants can be used, for example, for open gears.

NLGI 2 class materials can be used in a wide variety of components and mechanisms. At the moment, this class of greases is the most popular and widespread. Most often, such products are used in bearings for cars and trucks.

Composition and dosages

Materials of this variety are usually made on the basis of ISOSIN ™ base oils. They may also contain the following ingredients:

• lithium or inorganic thickeners;
• oxidation inhibitors;
• tacky and extreme pressure additives.

The color of materials in this class, depending on the brand, may be brown, yellow or blue.

Of course, use such oils in mechanismsshould be sufficient to reduce the friction force. The dosages of NLGI 2 oils depend on the particular unit in which they are used. When using such funds in this regard, one should be guided, first of all, by the passport and recommendations from the manufacturer of this particular device.

Greases of this type are designated by the abbreviation NLGI - from the name of the National Lubricating Grease Institute. After the letters in the marking, the number 2 is put - a specific class of material.

Quality requirements

Compared to conventional lubricating oils, NLGI lubricating oils have a longer service life in various assemblies and mechanisms. Of course, manufacturers involved in the manufacture of such materials are required to comply with certain requirements when they are released. Otherwise, the required finished product class will not be assigned. At the outlet, the lubricant must fully comply with NLGI standards.

NLGI 2 materials must satisfactorily lubricate components and mechanisms, including at high temperatures. High demands are also placed on their durability, degree of evaporation, oxidation, change in viscosity. To protect bearings and other components from corrosion and wear, such products should be as effective as possible.

Delo NLGI 2 Materials Specifications

Greases of this brand are produced by the American corporation Chevron, one of the largest in the world. For example, Chevron NLGI 2 Delo Greases EP, a multi-purpose grease manufactured by this manufacturer, is very popular on the market. Technicalcharacteristics of the material of this brand has the following:

• density - 940 kg/m3 at 20°C;
• maximum temperature range - from -40 °С to 130 °С (short-term).

The operating temperature of this material ranges from -30 °С to 117 °С.

Among other things, NLGI EP 2 lithium greases of this grade contain special extreme pressure additives containing sulfur and phosphorus. Such additives are corrosive to non-ferrous metals. Therefore, Chevron NLGI 2 Delo should not be used for worm gears that use copper-based metals, for example.

Using Chevron Delo Greases EP NLGI 2

It is recommended to use this oil:

• in mainline trucks, including automatic central lubrication systems and wheel bearings;
• in off-road vehicles used in agriculture, mining and agricultural industry;
• in commercial vehicles, including buses operating in harsh environments.

Also, these Delo NLGI 2 greases can be used in passenger cars in high-speed wheel bearings.

Shell NLGI Lubricants 2

The funds of this brand are produced by the Dutch company of the same name. Many of Shell's greases are not made with a lithium thickener, but with an inorganic non-soap thickener. That is, with increasing temperature, the consistency of suchfunds are not changing too much.

If desired, consumers can purchase, for example, NLGI 2 lubricants from this manufacturer:

• Shell Gadus S2 U460L 2 heat resistant.
• Shell Gadus S2 V100 2, which can also be used for life sealed sealed bearings.
• Shell Gadus S2 V145KP 2 for use in cold climates.

All of these products have excellent performance and have received great customer reviews.

Specifications Shell Gadus S2 U460L 2

Like Delo Grease EP NLGI 2, this material has been supplied to the domestic market for quite a long time. Previously, this product was called Shell Darina R 2. Shell Gadus S2 U460L 2 grease is made based on mineral oils using inorganic thickeners. Specifications it has something like this:

• working temperature - from -10 С to 180 °С;
• viscosity at 100 °C - 35;
• viscosity at 40°C - 460.

Use and Benefits of Shell Gadus S2 U460L 2

This tool can be used in a variety of industrial equipment, cars, commercial and trucks. Since this material is manufactured on a base oil with a high viscosity, it can also be used in heavily loaded low-speed bearings.

The main advantage of this lubricant is that it is usedit can even at very high temperatures. Under such conditions, it does not begin to melt as it does with similar products based on soap thickeners. With a change in temperature, the consistency of such a product practically does not change. In addition, this material is able to maintain its sealing ability even under strong vibrations.

What other NLGI 2 lubricants are available

Brands and varieties of materials of this class are produced by modern industry, so there are many. Of course, most often these are lubricants intended for various kinds of industrial mechanisms, special equipment and cars. But on sale today there are products of this category, intended for use in food equipment.

An example of such a material is NLGI 2 SKF LGFP 2 Grease. This non-toxic product is made from medical grade white oil using an aluminum complex soap. Such material, among other things, is compatible with food.

SKF LGFP 2 grease can be used, for example:

• in bakery equipment;
• cassette bearings Multi-pack;
• packaging machines;
• in filling machines;
• bearings in food industry conveyors.

The advantages of this grease include, among other things, a high degree of water resistance and a long service life. Big plusthis material is also considered neutral pH.
