Abstract
A plain bearing assembly of a rotational element on a bearing pin, the assembly including a bearing bolt, a bearing sleeve, which is non-rotatably mounted on the pin and which has a first bearing surface formed on its outer circumference, a rotational element which is rotatably mounted on the bearing sleeve and which has a second bearing surface that is formed on its inner circumference and that is slidingly mounted on the first bearing surface. The bearing pin has at least one lubricant channel opening onto the outer side of the pin and the bearing sleeve has a radial groove formed on its inner circumference, which groove communicates with the radial lubricant channel, and at least one opening branching off radially from the radial groove and opening towards the rotational element. The rotational element has a radial groove formed on its inner circumference and communicating with the opening and the first bearing surface is harder than the second bearing surface.
