A railway truck assembly includes a self-lubricating pad disposed therein. The self-lubricating bearing pad includes a first layer. The first layer includes a plurality of self-lubricating fibers inter-woven with a plurality of support fibers. The self-lubricating bearing pad includes a plurality of fiber layers. Each of the plurality of fiber layers includes a plurality of support fibers. The self-lubricating bearing pad includes one or more matrix layers communicating with one or more of the plurality of fiber layers. One or more of the matrix layers are infused into one or more of the plurality of fiber layers.

A spheroidal joint for a tuned mass damper system includes a base having a concave seat and a lubricious liner secured thereto. The base defines a first mounting portion under the concave seat and a circumferential rim opposite the first mounting portion. The concave seat tapers radially outward to define a chamfer which terminates at a radially inner edge of the rim. The spheroidal joint includes an inner member that has a convex seat. The inner member has a second mounting portion extending from the convex seat and an indentation circumferentially extending around the inner member between the convex seat and the second mounting portion. The indentation cooperates with the chamfer for misalignment of the inner member relative to the base. The convex seat slidingly engages the lubricious liner.

A self-aligning track roller bearing includes an inner member having a central axis and a convex surface and an outer member has a concave surface and is angularly displaceable relative to the central axis. A lubricious liner is positioned between the convex surface and the concave surface. The lubricious liner creates a force resisting movement of the inner member relative to the outer member. The bearing includes a snubber engaging an axially facing surface of the outer member and another snubber engaging another axially facing surface of the outer member. Outer rings are coupled to opposing axially facing surfaces of the inner member to retain the snubbers in engagement therewith. One or more of the snubbers are elastically deformable in response to angular displacement of the outer member and have a resilience set to overcome the force and urge the outer member to be concentric with the central axis.
