    Abstract: A headset of a bicycle includes a bearing base, a bearing cup, at least two sealing elements, damping fluid, and a bearing. The bearing base is adapted to be sleeved on a fork tube. The bearing cup is adapted to be abutted against an end, close to the fork tube, of a head tube, and a gap is formed between the bearing cup and the bearing base. The at least two sealing elements are disposed between the bearing cup and the bearing base, and the at least two sealing elements, the bearing cup and the bearing base seal the gap to form a damping section. The damping fluid is disposed in the damping section to provide damping force. The bearing is disposed between the bearing base and the bearing cup and is abutted against the bearing base and the bearing cup.

    Abstract: Provided is a floating-sleeve hybrid fluid bearing. The floating-sleeve hybrid fluid bearing may comprise: a bearing housing which is mounted by ring-coupling to the outer circumferential surface of a rotary shaft; and a floating sleeve which is mounted between the rotary shaft and the bearing housing so that there is a gap between the floating sleeve and the rotary shaft, and between the floating sleeve and the bearing housing, wherein the rotation of the floating sleeve is constrained by the bearing housing during the rotation of the rotary shaft, and one side of the floating sleeve in the circumferential direction is open in the radial direction.

    Abstract: A bearing element includes an inner surface (54) configured to receive a cylindrical shaft (18). The inner surface (54) includes a smooth profile having a plurality of sections (502). Each section (502) having a taper portion (506) between a first arc-span point (512) and a second arc-span point (514), a constant-radius portion (508) between the second arc-span point (514) and a third arc-span point (516), and a transition portion (510) between the third arc-span point (516) and a fourth arc-span point (518). An inner-surface radius dimension (520) changes from an inner-diameter major dimension to an inner-diameter minor dimension at the taper portion (506) and back at the transition portion.

    Abstract: A fluid bearing for operably connecting a shaft to a center housing of a turbocharger is provided. The fluid bearing includes a single-piece bearing sleeve defining a bore between first and second ends that each form a thrust face. The sleeve includes first and second bearing portions proximal to an associated one of the first and second ends, and a shank connecting the first and second bearing portions. Each of the first and second bearing portions includes an outer bearing surface defining a maximum outer diameter, and each of the first and second bearing portions includes an inner bearing surface defining a minimum inner diameter for radially supporting the shaft in the bore. The inner bearing surface is a continuous surface free of grooves. The sleeve has a wall thickness defining oil passages spaced from the inner bearing surface and configured to supply oil to the thrust face.
