Grease VNIINP – 502
instrument lubricant
Description
The main purpose of lubricants – reduced wear of the friction surfaces to extend the life of machine parts and mechanisms. In addition, the lubricant perform other functions. In some cases, they not only reduce wear as streamline it, preventing scuffing, galling and seizing of the friction surfaces. Lubricants to prevent the penetration of the friction surfaces of corrosive liquids, gases and vapors, as well as abrasive particles (dust, dirt and so on. P.).
