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.

Disclosed herein is a sliding member having an alloy overlay layer that comes into sliding contact with a counterpart member thereof and has improved fatigue resistance. The sliding member comprises a base material layer and an alloy overlay layer formed on the base material layer, in which the alloy overlay layer has a soft metal phase made of tin and precipitated in a metallic matrix phase made of aluminum, and when an average aspect ratio of the soft metal phase is defined as A, and its standard deviation is defined as Aσ, A+Aσ is 3.0 or less. In this case, the soft metal phase has a shape close to a sphere without elongating in a certain direction.

A sliding component including a sidewall including at least one low stiffness projection capable of elastic deformation, and at least one high stiffness projection capable of plastic deformation, where the low stiffness projection includes a radial face at an innermost or outermost surface adapted to contact a neighboring component.

Provided are sliding components capable of obtaining a stable low-friction effect under a wide range of conditions of use. A sliding component has a relatively sliding surface. A base material of one of the sliding components is coated with a graphite film, and the sliding surface of the other of the sliding components is made of the graphite film.

Embodiments of the invention relate to bearing apparatuses in which one bearing surface of the bearing apparatus includes diamond, while another bearing surface includes a non-diamond superhard material (e.g., silicon carbide). For example, a bearing apparatus may include a bearing stator assembly and a bearing rotor assembly. The bearing stator assembly and bearing rotor assembly each include a support ring and one or more superhard bearing elements generally opposed to one another. The bearing surface(s) of the rotor or stator may include diamond, while the bearing surface(s) of the other of the rotor or stator do not include diamond. Another bearing apparatus may include both thrust- and radial bearing components. The generally opposed thrust-bearing elements may include diamond, while the generally opposed radial bearing elements may not include diamond, but include a non-diamond superhard material, such as silicon carbide.
