Abstract

PURPOSE: A lubricant that is made by adding a specific amount of an oil-soluble polymer to a purified mineral oil of a specific viscosity as a base, thus reducing the friction loss on plain bearings of large machines for heavy industries where the turbulent lubrication is caused.
CONSTITUTION: (A) A purified mineral oil base with a dynamic viscosity of 10W 10,000cst at 40°C and a viscosity index or 80 is combined with (B) 1W1,000ppm of an oil-soluble polymer with a viscosity-average molecular weight of more than 50,000, preferably more than 200,000 selected from the group consisting of 2W20C olefin polymers, 4W5C diolefin polymers, 8W20C aromatic vinyl polymes and polymers of acrylic ester or methacrylic ester of a 1W18C aliphatic monohydric alcohol to produce the objective lubricant for plain bearings.
