Abstract
A bearing shell segment for internal combustion engines, composed of a body defining an inner surface that receives a coating and makes contact with a layer of lubricant oil film and an opposite outer surface, associable to a bearing, an inner surface having at least a first area substantially free from the compression load coming from the movement of the piston by the explosion of air-fuel mixture, and a second area which receives compression load coming from the movement of the piston by the explosion of air-fuel mixture. The first area has at least a surface portion to capture foreign particles present in the layer of lubricant oil film, the surface portion having cavities positioned so as to enable at least one foreign particle to be captured and withheld while moving towards the flow of lubricant oil, before reaching the second area.
