A seat track assembly including a first rail and a second rail spaced apart by a distance and extending parallel with respect to one another, wherein at least one of the first and second rails having a first receiver, a second receiver, the first and second receivers longitudinally translatable with respect to each other, and a sliding member disposed therebetween, wherein the sliding member defines an aperture extending at least partially therethrough.

In one aspect, an improved electric transmission assembly is provided that includes a hydrodynamic bearing. The electric transmission assembly includes a stator arranged inside of an outer housing. A rotor is configured to be rotatably driven by the stator. The rotor can include a rotor shaft having a first gear configured to driveably engage with a differential. A hydrodynamic bearing is arranged between the rotor shaft and the outer housing. The hydrodynamic bearing is formed from a non-conductive material. Specifically, the hydrodynamic bearing can be formed from a polymeric or plastic material. In one aspect, the hydrodynamic bearing is formed from a non-metallic material.

A half bearing has a concave portion, a concave portion, and a concave portion penetrating from the outer circumferential surface to the inner circumferential surface, and the washer has a convex portion, a convex portion, and a convex portion on the inner circumferential surface side. The washer is moved to the outer circumferential surface side of the half bearing in a bent state, the convex portion is inserted into the concave portion, the convex portion is aligned with the position of the concave portion, and the convex portion is aligned with the position of the convex portion. Next, when the half bearing returns to its shape before being bent, the convex portion is accommodated in the concave portion, and the convex portion is also accommodated in the concave portion. Even if an axial force acts on the sliding bearing, the protrusion, the protrusion, and the protrusion engages with the concave portion, the concave portion, and the concave portion, so that the washer and the washer are not detached from the half bearing.

Embodiments of the present disclosure provide for mixtures, methods for making mixtures, articles, methods for making articles, and methods of using articles.

A sliding member includes: a lining layer formed from an alloy having a predetermined shape; and an overlay layer formed on an inner circumferential surface of the lining layer, the overlay layer being formed of a resin, the overlay layer sliding with a shaft, the overlay layer including a raised portion a height of which in a predetermined area including each of an edge in an axial direction of the shaft is greater than a height of another area of the overlay layer.

A thrust washer is provided with a ring-shaped portion that surrounds an insertion hole, the thrust washer is provided with a sliding surface and an oil groove configured to allow lubricating oil to flow in, the oil groove is provided with an opening portion configured to allow the lubricating oil to flow in from the insertion hole side in an inner peripheral end side, an outer periphery end side of the ring-shaped portion of at least one of the oil groove is provided with an oil stop wall which is configured to suppress flow of the lubricating oil toward an outer periphery side of the ring-shaped portion, and a sliding area ratio of each of the sliding surfaces to a projection plane in plan view of the ring-shaped portion is provided within a range of from 60% to 85%
