Abstract: 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.
