Grease MS-1000. Characteristics and application

Main Components

The main components of this grease are lithium soaps, molybdenum disulfide, as well as auxiliary substances that give MS-1000 viscosity stabilization and heat resistance properties.

Lithium organometallic compositions, in comparison with others, have a number of advantages:

1. Availability of production technology, and, consequently, low cost.
2. Increased mechanical stability.
3. Resistant to fluctuations in temperature and humidity.
4. The ability to form stable compositions with other substances of the same class.

Lithium soaps that are part of the MS-1000 lubricant are obtained synthetically, but they also contain natural components, which allows this composition to be chemically indifferent not only to metals, but also to plastics or rubber.

The presence of molybdenum disulfide is indicated by the dark color of the substance. Positive properties of MoS₂ are especially pronounced at high pressures, when the smallest wear particles form on the friction surfaces (for example, bearings). Contacting with molybdenum disulfide, they form a strong surface film, which subsequently takes all the loads, preventing damage to the metal surface. Thus, MS-1000 belongs to the class of lubricants that restore the original state of the surface.

Features and Features

Technical requirements for MS-1000 grease are regulated by DIN 51502 and DIN 51825. It is produced according to TU 0254-003-45540231-99. Lubrication performance indicators are as follows:

1. Lubrication class - plastic.
2. Temperature limits of application - from minus 40^°C to plus 120^°C.
3. Base viscosity at 40^°C, cSt - 60 ... .80.
4. Thickening temperature, not less than 195^°C.
5. Critical load on the lubricated part, N, no more than - 2700.
6. Colloidal stability,%, not less than - 12.
7. Moisture resistance, %, not less than - 94.

Thus, MS-1000 is an excellent alternative to traditional grease or lubricants such as SP-3, KRPD and others, which were previously recommended for friction units operating at constant contact pressures.

The manufacturer of MS-1000 grease, VMP AUTO LLC (St. Petersburg), notes that this substance not only serves as an intermediate barrier between the rubbing surfaces of steels, but also provides reliable sealing between parts.

In product reviews, it is noted that the lubricant in question effectively replaces most other lubricants that are recommended for automotive equipment, which facilitates its routine maintenance. By the way, the intervals for such maintenance can (without compromising quality) be increased, since during the tests the restoring ability of the lubricant to build up the surface layers of bearings due to particles - wear products was practically proven.

Application

Metal-cladding lubricant MS-1000 is recommended for:

• intensive modes of operation of cars;
• heavily loaded parts of industrial gearboxes (especially with screw and worm gears);
• high power electric motors;
• friction guides for heavy forging and stamping equipment and machine tools;
• rail transport systems.

It is important that the use of this substance does not complicate normal maintenance procedures, since, as follows from the reviews, MC-1000 grease is environmentally friendly and easy to use.

Some limitation is the high price for the product. Depending on the packaging option, the price is:

• in disposable sticks - from 60 to 70 rubles, depending on the mass;
• in tubes - from 255 rubles;
• in packages - from 440 rubles;
• in containers, jars 10 l - from 5700 rubles.

Recommendations of some users are known that MS-1000 mixes well with cheaper grease such as Litol-24, and without compromising quality.
