  • Corrosion resistance is required as a fundamental property of lubricating oils in machinery installations so as to maintain performance. This is because the lubricating oil temperature within tanks in mechanical apparatus rises and falls in accordance with conditions of use, and therefore the lubricating oil within the tanks may be subject to admixture with condensed water, or to admixture with moisture because of leaks from cooling water pipes.
  • This invention is intended to obtain an industrial lubricating oil which reduces the friction coefficient exhibited by the lubricating oil and which has high energy-saving properties. If such a lubricating oil composition is used as a hydraulic oil in hydraulic apparatus, it is also intended to make it possible to control the hydraulic apparatus with precision and without giving rise to chatter, vibration, squealing and other abnormal sounds in the cylinders, as well as inhibiting the occurrence of rust and imparting good corrosion resistance.
