Abstract: A process for manufacturing a bearing. The bearing may be used in a tool disposed within a bore hole. The process comprises providing a tubular sleeve and applying a hard facing material on the outer diameter of the tubular sleeve so that the hard facing material is fused onto the outer diameter, and thereafter applying a material layer on the outer diameter so that the material layer is fused onto the outer diameter. The method further includes machining the outer diameter so that a portion of the material layer is removed, and then machining the inner diameter so that only the hard facing material is left as an inner diameter. The method further includes machining the outer diameter and the inner diameter in order to form the bearing. In the most preferred embodiment, the method further includes placing the bearing into a housing, and inserting a mandrel into the bearing, and wherein a hard coating of the mandrel abuts the bearing. A mud motor for rotating a bit in a well bore is also disclosed.

Abstract: In an assembly made up of a spindle formed integrally with a revolving cutting element (10), the longitudinal axis of the spindle being the axis of rotation of the cutting element, the spindle is set into a cylindrical bearing (30). The bearing (30) is fixed in the main body (4) of the bit. The bearing element (30) and a plate (60) form a thrust surface with the end of the bearing (30) at right angles to the axis of rotation of the spindle, which the other end of the bearing element made with the flange projecting outwards is held in the cutting element (10) by means of the retaining ring (20) which is fixed in the cutting element. A thrust surface (Y) at right angles to the axis of the rotation of the spindle is created between the top end of the bearing element (30) and the cutting element (10) and another (X) between the retaining ring (20) and the main body (4) of the bit. By maintaining the spindle centrally in the bearing the wear on the bearing is radically reduced.
