As a basic study for making clear the effects of load distribution in the tooth trace direction on the anti-seizure capacity of lubricating oil, the effects of contact width on asperity interaction and the anti-seizure capacity under uniform bearing have been studied for a gear base oil with a two-cylinder test rig at a high specific sliding. The seizure took place from the mixed lubrication state. Though the asperity interaction is high at a small contact width, the effects of contact width on the asperity interaction diminishes as the contact width is enlarged. At a small surface roughness, the seizure load and the outer surface bulk temperature just before seizure increase as the contact width is enlarged. On the other hand, at a large surface roughness, in the higher sliding velocity range, the seizure load diminishes as the contact width is enlarged over a certain value, and the outer surface bulk temperature just before seizure is lower than that at the small one.
