Patent ID: 8851755

Claim:
A self-aligning track roller bearing comprising: an inner member having a central axis and a convex arcuate bearing surface, an outer member positioned around the inner member coaxially with the central axis, the outer member having a concave arcuate bearing surface that cooperates with the convex arcuate bearing surface such that the outer member is rotatably mounted about the central axis of the inner member and angularly displaceable relative to the central axis; a first lubricious liner positioned between the convex arcuate bearing surface and the concave arcuate bearing surface, the first lubricious liner defining a first friction force for resisting movement of the outer member relative to the inner member; a first snubber ring engaging a first axially facing surface defined by the outer member, the first snubber ring being manufactured from a resilient material; a second snubber ring engaging a second axially facing surface defined by the outer member, the second snubber ring being manufactured from the resilient material; a first outer ring coupled to a third axially facing surface defined by the inner member, the first outer ring configured to retain the first snubber ring in engagement with the first axially facing surface; a second outer ring coupled to a fourth axially facing surface defined by the inner member, and the second outer ring configured to retain the second snubber ring in engagement with the second axially facing surface; and at least one of the first snubber ring and the second snubber ring are elastically deformable in response to angular displacement of the inner member and have a resilience of a predetermined magnitude to overcome the first force and urge the inner member to be concentric with the central axis.
