Claim:
Bearing shell segment ( 100 ) for internal combustion engines, composed of a body (C) defining an inner surface ( 1 ) that receives a coating and makes contact with a layer of lubricant oil film and an opposite outer surface ( 2 ), associable to a bearing, the inner surface ( 1 ) having at least a first area ( 10 ) substantially free from a compression load from a movement of a piston by explosion of an air-fuel mixture and a second area ( 20 ) that receives compression load coming from the movement of the piston by the explosion of air-fuel mixture, the first area ( 10 ) having at least a surface portion ( 3 ) to capture foreign particles present in the layer of lubricant oil film, wherein the surface portion ( 3 ) comprises a plurality of cavities ( 4 ) positioned so as to enable at least one foreign particle to be captured and retained by at least one of the cavities ( 4 ) while moving towards the flow of lubricant oil, before reaching the second area ( 20 ).
