ABSTRACT:
In a multiple piston axial type pump, a support saddle and cooperating swash block are enclosed by a housing. A pair of arcuate bearing shells are attached to spaced apart bearing seats formed on the swash block. The bearing shells contact load bearing surfaces on the support saddle. The length of each of the bearing shells is less than the length of the support saddle load bearing surfaces so that the facing surfaces of the bearing shells are always in complete contact with the load bearing surfaces throughout the complete range of relative positions of the support saddle and the swash block.
