Abstract: The bearing element for the small end of a connecting rod (2) comprises a bearing surface (1a), at least one oil supply hole (5a, 5c) for allowing lubricating oil to be supplied radially through the bearing element (1) onto the bearing surface (1a), and an oil groove (6) connected to said oil supply hole (5a, 5c) for distributing lubricating oil on the bearing surface (1a), the oil groove (6) comprising a first portion (6a), which extends from the oil supply hole (5a, 5c) to a direction, which allows in a mounted state of the bearing element (1) lubricating oil to flow from the oil supply hole (5a, 5c) along the first portion (6a) by gravity, and a second portion (6b) connected to the first portion (6a). The second portion (6b) is shaped so that in a mounted bearing element (1) acceleration of the piston (4) to- wards bottom dead center causes part of the lubricating oil to be trapped in the second portion (6b).
