A bearing member 1 is provided with a coating layer 3 on an inner circumferential surface of a shaft hole 1A into which a shaft body 2 is to be fitted. The coating layer 3 is composed of a metal base material 3A and a heat conductive material 3B that is dispersed in the base material 3A and that has a thermal conductivity relatively higher than that of the base material 3A. The heat conductive material 3B has lengths Lb and Lc in directions B and C along a surface of the coating layer 3, longer than a length La in a thickness direction A of the coating layer 3, whereby thermal conductive characteristics in the directions B and C along the inner circumferential surface of the shaft hole 1A are enhanced. Thus, heat dissipation is improved, whereby temperature rise due to sliding contact with the shaft body 2 is suppressed, and seizure resistance is improved.

A spherical ball joint having an inner ring and an outer ring that cooperate by way of respective truncated spherical contact surfaces, the inner ring having a central bore with a cylindrical bore portion. The spherical ball joint includes a cylindrical sleeve mounted securely in the cylindrical bore portion, the sleeve configured to be mounted around a shaft, the sleeve being made of a wear-resistant material different from that of the inner ring.

A bushing for aircraft landing gear includes a cylindrical wall having an interior surface defining a bore extending between a first and second axial end thereof and a cylindrical recess extending into the interior surface. The bushing includes a cylindrical self-lubricating liner which is substantially flush with the interior surface is disposed in the recess. The cylindrical wall includes a flange that has an annular recess that receives an annular self-lubricating liner that has a planar axial bearing surface. The planar axial bearing surface is coplanar with an inboard axial surface of the flange. The bushing has an electrically conductive path that conducts electrical current and that extends around the cylindrical self-lubricating liner and the annular self-lubricating liner and through the cylindrical wall and the flange.

A casing for a shaft assembly, a shaft assembly, a method of forming a casing, and a drive assembly. The casing may generally include a liner defining a central passage and having a body and an outwardly-extending leg (e.g., extending circumferentially about and/or axially along the body), and a cover extending circumferentially about and axially along the liner.

A sliding bearing includes a bearing surface which comprises a material in which an alloy material based on CuSnX (0.01<X<9), CuNi2Si, or CuFe2P is used. A method for producing such a sliding bearing and a use for CuNi2Si, CuFe2P, and CuSnX in a sliding bearing is also provided.

Provided is a bearing for a motor-type fuel injection pump. This bearing is composed of a Cu—Ni-based sintered alloy, inexpensive and has a superior corrosion resistance and abrasion resistance. The bearing contains 10 to 20% by mass of Ni, 2 to 4.5% by mass of Sn, 0.05 to 0.4% by mass of P, 2 to 7% by mass of C, and a remainder consisting of Cu and inevitable impurities. The bearing has a metal structure where Sn is uniformly dispersed and distributed in a metal matrix, and has a porosity of 7 to 17% where a free graphite is dispersed and distributed in pores.

A sliding member includes a back-metal layer and a sliding layer made of a copper alloy. The back-metal layer is made of a hypoeutectoid steel including 0.07 to 0.35 mass % of carbon, and has a structure including a ferrite phase and pearlite. The back-metal layer includes a pore existing region including a plurality of closed pores that are not open to a bonding surface when viewing a cross-section perpendicular to a sliding surface. The closed pores have an average size of 5 to 15 μm. The pore existing region extends from the bonding surface toward an inner portion of the back-metal layer, and has a thickness of 10 to 60 μm. A ratio V2/V1 of a total volume V2 of the closed pores to a volume V1 of the pore existing region is 0.05 to 0.1.

A bearing bushing (1) and to a method for manufacturing a bearing bushing are provided. The bearing bushing includes a wire article (2) formed from knitted wire mesh or knitted wire fabric (6) and compressed into a dimensionally stable compressed product (3). The bearing bushing can be provided for supporting a throttle valve used in high-temperature applications. The wire article (2) is formed from a stainless steel. Existing voids (10) of the compressed product (3) are filled with solder (4).

The Cu-based sintered sliding material has a composition including, by mass %, 7% to 35% of Ni, 1% to 10% of Sn, 0.9% to 3% of P, and 0.5% to 5% of C, with a remainder of Cu and inevitable impurities, wherein the Cu-based sintered sliding material includes a sintered body including: alloy grains that contain Sn and C and contain a CuNi-based alloy as a main component; grain boundary phases that contain Ni and P as main components and are dispersedly distributed in grain boundaries of the alloy grains; and free graphite that intervenes at the grain boundaries of the alloy grains, the Cu-based sintered sliding material has a structure in which pores are dispersedly formed in the grain boundaries of the alloy grains, and an amount of C in a metal matrix including the alloy grains and the grain boundary phases is, by mass %, 0.02% to 0.20%.

A sintered bearing is made of a sintered compact containing nickel silver (CuNiZn) as a base. In the sintered bearing, P is not added in the sintered compact. Alternatively, a content of P in the sintered compact is less than 0.05 mass % in terms of mass ratio to a total mass. Consequently, crystal grains constituting the sintered compact can be micronized. In particular, in the sintered bearing, an average crystal particle diameter of the crystal grains constituting the sintered compact is 20 m or less. Consequently, the mechanical strength and the vibration resisting properties can be improved, and the rotation shaft can be prevented from being damaged.
