Description

technical field [0001] The invention belongs to the field of industrial lubricating oil, in particular to a bearing lubricating oil composition and a preparation method thereof. Background technique [0002] Bearing is a component that fixes and reduces the load friction coefficient in the process of mechanical transmission. It is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction of the equipment during the transmission process. Mechanical load friction coefficient. During the movement of the bearing, in order to reduce friction, buffer pressure and prolong the service life of the bearing, lubricating oil is required. According to the characteristics of the bearing movement, in addition to anti-pressure and anti-friction, the lubricating oil also needs to have good low-temperature start-up and anti-corrosion performance, so as to adapt to the long-term use of the bearing under var...
