1. A plain bearing bush, comprising a cylindrical main body having a first shell surface and a second shell surface, said first and second shell surfaces including a plurality of exchange bores for a lubricant, at least one of the exchange bores having a first diameter on the first shell surface and a second diameter on the second shell surface, with the second diameter being greater than the first diameter for an increase in a load-bearing capability of the plain bearing bush, wherein two of the exchange bores are arranged in axial spaced-apart relation and connected to one another by a pocket depression.
