Now, the primary oils used as industrial lubricating agents are Liquid Petroleum and chemical synthetic oils. But, because these oils are contributed to global warming and serious environmental pollution, the edible vegetable oil is expected to serve as one of the alternatives to these oils. Formerly-performed research found that canola, sesame, and econa oils had an equivalent effect to the Liquid Petroleum tested. Liquid Petroleum caused seizure in a high aspect pressure, and a result that the edible vegetable oil had better durability performance was given. In this research, I perform a design and production of a four-ball tester examining in a more severe condition, and I was aimed at performing the endurance test of the lubricant with this examination machine. This research found that Liquid Petroleum reached limit load in all conditions earlier than all edible vegetable oil. In addition, econa oil reached limit load by number of revolutions 500 and 750 min^<-1>. Furthermore, the sesame oil and the Canola oil did not reach limit load in this condition.
