摘要： The present invention refers to a 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, an inner surface (1) having at least a first area (10) substantially free from the compression load coming from the movement of the piston by the explosion of air-fuel mixture and a second area (20) which 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, the surface portion (3) comprising a plurality of cavities (4) positioned so as to enable at least one foreign particle to be captured and withheld by at least one of the cavities (4) while moving towards the flow of lubricant oil, before reaching the second area (20).
