The family of lubricants and greases refers to a category of products used to reduce friction and wear on moving surfaces, as well as to properly protect and maintain mechanical components. These products are widely used in various sectors, including the automotive industry, manufacturing industry, heavy machinery, and the marine industry. Lubricants are substances that are applied between two moving surfaces to reduce friction and wear. They can be liquid, such as lubricating oils, or solid, such as lubricating powders. Liquid lubricants are made up of a lubricant base, which can be mineral, synthetic or vegetable, and is mixed with additives to improve its properties, such as resistance to high temperatures, protection against corrosion and load capacity. Solid lubricants, like greases, are composed of a thickener and a base lubricating oil.
