    Abstract: A bearing assembly includes an outer race and an inner race. The outer race has a body extending between a pair of axial faces and defines a radially-inward facing bearing surface. The inner race is received in the outer race and has a radially-outward facing bearing surface that bears against the radially-inward facing bearing surface of the outer race. The radially-outward facing bearing surface has one or more flat surfaces removed from it. These flats on the inner race can reduce the dimensional entry requirements for insertion of the inner race into the outer race and either permits the receiving slots in the outer race to be reduced in dimension (thereby relatively thickening the wall of the outer race, which structurally strengthens the outer races) or permits the receiving slots to be eliminated altogether.

  • Patent number: 9151290
    Abstract: A cylinder body includes a cylinder hole and a discharge flow passage. The cylinder hole receives a plunger and forms a pressurizing chamber in one axial end portion thereof. The discharge flow passage is connected to the pressurizing chamber and is adapted to guide and discharge the pressurized fuel from the pressurizing chamber to an outside of the housing. A connection opening of the discharge flow passage is formed in a hole wall of the cylinder hole. A pressure is applied to a predetermined prestressing subject area in the hole wall of the cylinder hole and a passage wall of the discharge flow passage through autofrettage to generate a residual compression stress in the predetermined prestressing subject area and thereby to form a prestressed area of a final product. The prestressing subject area includes an inner peripheral edge of the connection opening.

    Abstract: A rotary cutting tool having a monolithic carbide cutting member defining a carbide cutting head and a carbide shaft extending outwardly from the cutting head. The shaft includes a conduit in fluid communication with a port for delivering coolant and/or lubricating fluid to an interface between the cutting tool and a work piece. The cutting head defines a peripheral portion and a plurality of carbide cutting edges alternating with flutes in the peripheral portion. The cutting head, the shaft, and the cutting edges are formed integrally with one another. A shank portion defines an elongated bore, and the shaft is received in the bore in a shrink-fit relationship, wherein the shaft of the cutting member is fixed against movement relative to the shank portion.
