To lubricate the axle bearing of the Shinkansen vehicles, it is essential to improve the thermal oxidation stability of the lubricating oil in terms of speed-up, and also it is important to improve the durability to extend the intervals for oil-changes. In order to deal with such requirements, application of synthetic base oil was effective. But we tried correspondence by the mixture of synthetic base oil and mineral base oil to suppress the cost of the lubricating oil. Therefore, we selected poly-a-olefin (PAO) for the synthetic base oil, and verified that upgraded performance with the mixture of PAO and mineral base oil. Then, we experimentally manufactured the lubricating oil for axle box that applied such mixed base oil. Consequently, we confirmed experimental lubricant was excellent in thermal oxidation stability and durability. We report the consequences herewith.
