Types of lubricants for large open gear

(1) Asphalt based products. It is directly extracted from crude oil and contains extreme pressure additives and organic solvents. In addition, it is difficult to deal with the leakage of oil. At present, the national environmental protection policy has been tightened.

(2) Liquid lipid products. The main components are high viscosity base oil and thickener, and contain a certain proportion of solid lubricants and extreme pressure additives. Due to the high bearing capacity, thick oil film thickness, high temperature resistance and water washing resistance, the four ball sintering load is high and has certain sealing performance.

(3) Pure oil products. It is characterized by high viscosity of base oil, thick oil film during friction, transparent or light brown color, adding extreme pressure additives to increase its bearing capacity, and high sintering load of four balls.
