Abstract
A gear pump bearing block has a bush formed of antifriction alloys. The bush has a cylindrical portion providing a bore adapted to receive a bearing shaft of a gear of the pump. It further has a thrust face at the end of the cylindrical portion, the thrust face being adapted to slidingly engage with a side surface of the gear. The bush has an inner component providing the bore, and an outer component forming a radially outer surface of the cylindrical portion. The inner and outer components are formed of respective lead bronze alloys, the lead bronze alloy of the outer component having a higher lead content than the lead bronze alloy of the inner component.
