There is disclosed a sliding bearing provided with a sliding bearing layer and a back metal layer bonded to the outer face of the sliding bearing layer, the back face of which back metal layer being coated with a phosphate coating at a portion where fretting wear is apt to occur while coated with a coating of a thermally good conductor at another portion where no phosphate coating is provided, whereby seizure resistance as well as fretting resistance is improved because the dispersing of heat can be improved by the coating of the thermally good conductor.

Sliding bearing and sliding bearing structure

A sliding bearing assembly excellent in fretting resistance which comprises a sliding bearing and a housing, the sliding bearing having a bearing alloy layer in the internal surface of its backing metal layer and the internal surface of the housing being fitted with the sliding bearing, wherein a phosphate film is formed on the back of the backing metal layer of the sliding bearing, the phosphate film being composed of needle crystals or columnar crystals which have a particle size of not more than 30 .mu.m when observed from the back of the backing metal layer.
