<p>There is provided a plain bearing in which 0.3 to 25 vol.% of hard particles, having a mean particle diameter of not more than 1.5 Ám, are dispersed in a main load portion (M) of the overlay, so that the main load portion is formed into a hard region (4a) harder than the other portion (4b) of the overlay. With this construction, the main load portion (M) is enhanced in wear resistance while the other portion (4b) is enhanced in foreign matter embeddability. Therefore, there is provided the plain bearing which is less liable to undergo seizure due to abnormal wear even if solid foreign matters are included into lubricating oil, thus exhibiting excellent wear resistance and foreign matter embeddability.</p> |
