Maxtop gear bearing circulating oil (PAG type) is made of polyalkylene glycol synthetic oil as base oil, and added with extreme pressure, anti-wear, antioxidant and other additives. Gear bearing circulating oil is a highly efficient lubricating oil designed for closed cycle lubrication scenarios such as gear box and bearing system. The core function is continuous lubrication, heat dissipation and cooling, anti-wear and prolong equipment life. It can cover key parts such as gear meshing surface and bearing raceway through the circulation system to ensure stable operation of equipment under harsh conditions such as high speed, heavy load and high temperature.
