All metal mechanisms during their work are subject to friction and gradually fail. During this process, metal parts heat up and lose their normal physical properties, which can adversely affect the entire mechanism and render it inoperative. To avoid this, since ancient times, people invented and used various types of materials that give parts of mechanisms the ability to work without heating during friction.
Vegetable oil and derivatives of animal fats and dairy products were used as lubricants, but they did not produce a long-term effect. Gradually, closer to our time, people learned to process products of petroleum origin and to separate from them various types of materials for lubrication. One of these materials in our time has become lubricant number 158. This is a fairly common type of lubricant, which has found wide application in the processing of metal parts.
Grease No. 158
This type of lubricant is made from high-quality oil-based oils with the addition of special potassium-lithium soap, which is a thickener. This is done for a variety of operating conditions. Lubricant No. 158 is manufactured at one of the most modern enterprises in our country, and is produced on the basis of advanced technologies, using only high-quality materials.
In appearance, the product is a soft, creamy blue texture. Color gives it the presence of copper, its components play the role of a thickener. Use this type of lubricant as anti-friction in automotive technology.
Grease benefits
Lubricant No. 158 has high mechanical stability and withstands the oxidation process for a long time under the influence of various aggressive media. It is practically not subject to destruction under the influence of water, it perfectly prevents such a negative effect as wear of metal parts of mechanisms. It has high sliding properties during friction of parts, the range of operating temperatures is quite wide and has values from -30 to +110 ° C. After application to working parts, it retains its sliding properties for a long time and does not spread, thereby protecting the parts from premature wear during operation. Another advantage can be considered low cost, which makes it common.
Characteristics
The lubricant characteristics of No. 158 are not much different from other similar materials. It has a color that varies from light blue to dark blue, it depends on the amount of copper-containing thickener in it. As soap, potassium-lithium compounds are used, according to the consistency according to NLGI it has indicators 1-2. The oil on the basis of which the lubricant is produced has a mineral origin and a homogeneous structure, is not divided into components.
Grease No. 158 has a tensile strength at 50 ° C not lower than 160 Pa, while the effective viscosity at 0 ° C and an average strain rate gradient of 10 s -1 is not more than 400 Pa * s. In this lubricant there is a mass fraction of free alkali calculated on NaOH not more than 0.1%. Lubricant No. 158 contains a small amount of water, which does not affect the metal parts of the mechanisms.
Application
Lubricant No. 158 found its main application in automotive tractor equipment. In alternators, starter and magneto, it is perfectly preserved for several years without replacement, preventing the failure of the rolling bearing. This allows for a long time not to lubricate some components and mechanisms of automotive machinery. Subject to operating conditions of lubricant No. 158, it allows uninterrupted operation of machine mechanisms for 300 km.
