Greases Are Pasty Lubricants for Industrial Use, Providing Physical Sealing, Structural Stability, and Resistance to Water Washing.
Greases are essential in the industrial world, playing a crucial role in the maintenance and operation of various equipment. They offer physical sealing, structural stability, and resistance against external factors such as water washing. Their application in mechanical components, such as bearings and gears, ensures the operational continuity of machines.
Known for being pasty lubricants, greases are widely used in about 80% of industrial mechanical elements. Due to their high viscosity, these compounds for the industrial segment are ideal for various machinery systems. In addition to protection, greases also enhance operational efficiency, ensuring that machines operate with less friction and greater longevity. Thus, the proper use of greases significantly contributes to the reduction of maintenance costs and increased productivity.
Properties of Greases and Their Application in Industry
The properties of greases provide an efficient physical sealing for various structures, preventing the entry of contaminants. Greases exhibit resistance to water washing and have the ability to remain at the application site, even when used in vertically installed positions. This behavior makes these pasty lubricants extremely advantageous in industrial environments where durability and resistance to contamination are essential.

Composition and Manufacturing of Greases
According to the renowned brand Mobil™, with over 150 years of tradition in innovation and quality, greases are produced from three fundamental components: base oil, thickener, and additives. The interaction between these elements gives greases their main characteristic, namely, structural stability. This stability refers to the consistency that the grease maintains even when subjected to different mechanical stresses. Mobil™ lubricants emphasize that careful selection of these components is crucial for the performance of greases.
Challenges and Maintenance of Greases
It is important to note that softening of greases in bearings can eventually lead to leakage, requiring more frequent maintenance and continuous replenishment. This is crucial to prevent premature failures resulting from the lack of lubricant in the rolling elements. To make this maintenance less costly and more efficient, several strategies are adopted. Among the main ones is the careful selection of the composition of thickeners and the optimization of the manufacturing process.
Importance of Careful Selection and Optimization in Grease Production
Vitor Viana, responsible for Marketing in the industrial lubricants category at Mobil™, explains that the development of good mechanical stability in greases depends on the precise selection of thickeners and the optimization of the manufacturing process. This combination not only ensures the effectiveness of the product but also helps to reduce maintenance costs, which can exceed R$ 20 million annually in the industry, according to a survey by Mobil™. Therefore, it is essential to pay attention to the characteristics of the grease, including its components and structural stability, to avoid unnecessary expenses.
Functions of Greases in Comparison to Fluid Lubricants
Although greases do not perform cooling and cleaning functions, associated with the use of fluid lubricants, they are capable of performing all other functions that these lubricants fulfill. Pasty lubricants thus offer excellent performance in many industrial applications, ensuring proper lubrication and extending the lifespan of equipment.
