A sliding bearing having excellent initial conformability and seizure resistance as well as high durability and heat resistance is provided. A sliding bearing comprising a coating layer containing a resin and a solid lubricant formed on a bearing alloy layer, characterized in that the resin of said coating layer is a resin having a glass transition temperature of from 150&#xb0; C. to 250&#xb0; C. which has a great elongation at high temperatures.

Sliding bearing

A helical grooveB is formed in the sliding surfaceA of a sliding bearingover the entire axial region thereof. To establish the height of a peaka defined by the helical grooveB, an imaginary reference line L extending parallel to the axis is formed which is determined such that the total cross-sectional area of all the peaksa is equal to the total cross-sectional area of all the valleysb when the helical grooveB is considered in axial section. A height, as measured from the reference line L to the topa' of the peaka is chosen in the range of from 1 to 8 &#x3bc;m. The space created by forming the valleysb allows the supply of lubricant oil to be increased, thereby simultaneously achieving a reduction in the frictional resistance and the occurrence of an impact sound.
