To realize tribosystem which is environment-conscious and is safe from health damage, some vegetable oils are applied to base oils for commercial lubricants. However, performance of the tribosystem using vegetable oils hasn't been clear yet. We investigated transition of lubricity of vegetable oil (rapeseed oil) related to oxidation. The oxidized rapeseed oil showed lower friction coefficient and lower wear than the normal rapeseed oil under both temperature conditions of 40 and 100 Celsius degree on combination of phosphor bronze plate and bearing steel ball. On the other hand, while lubrication condition of combination of bearing steel plate and bearing steel ball with the oxidized oil was superior than the normal oil under temperature condition of 40 Celsius degree, lubrication condition of the combination with the oxidized oil became worse than the normal oil under temperature condition of 100 Celsius degree.
