The bore of a bearing bush (11 or 13) for a gear pump has radially inwardly extending projections (20, 21) spaced equi-angularly on either side of a line of action (15) of an operating load on a gear shaft (10) within the bore, to maintain the shaft (10) at an effective distance from a recess (16) to which fluid under pressure is supplied, the recess being located on the line of action (15) of the load and diametrally opposite the projections (20,21). |
