The main purpose of lubricants is to reduce the wear of friction surfaces to extend the service life of machine parts and mechanisms. Along with this, lubricants perform other functions. In some cases, they do not so much reduce wear as they streamline it, preventing scoring, jamming and jamming of friction surfaces. Lubricants prevent the penetration of aggressive liquids, gases and vapors, as well as abrasive particles (dust, dirt, etc.) to the friction surfaces.
