Abstract
A bearing carrier has a bearing body including a first material. The bearing body has an exterior surface defining a bridge land with a finger cut and rotatably supports a first and second gear. The first and second gears intermesh with one another for pressurizing fluid traversing the gears between a fluid inlet and a fluid outlet defined in a housing enveloping the bearing carrier. The bridge land is defined in a second material integral with the first material. Methods fabricating a bearing carrier for a gear pump are also disclosed.

A method of fabricating a bearing carrier, comprising:
- defining a near net shape contour of a bridge land in a surface of a second material integral with an underlying first material.
A method of fabricating a bearing carrier, comprising:
- at a bearing body formed from a first material, the bearing body having a bridge land with a finger cut to channel fluid pressurized by intermeshing of gears rotatably supported by the bearing carrier into an outlet defined by a housing enveloping the bearing carrier,
- coupling a second material to the first material;
- and
- defining a near-net shape contour of a bridge land in a surface of a second material integral with an underlying first material.

- scanning the bridge land of the bearing body;
- removing a portion of the first material defining the bridge land;
- coupling a second material to the first material;
- and
- defining a near-net shape contour of a bridge land in a surface of a second material integral with an underlying first material.
