A track link rail surface and roller interface (400) includes a first roller (402) including a cylindrical configuration defining a radial direction (R), a longitudinal axis (A), a circumferential direction (C), and a plane (RA) containing the radial direction (R) and the longitudinal axis (A). The first roller (402) includes a first track link rail engaging surface (404) including a first concave arcuate surface (406) defining a first concave radius of curvature (408). The interface (400) includes a first track link (410) including a first track link rail surface (412) including a first convex arcuate surface (414) defining a first convex radius of curvature (416) that is less or equal to the first concave radius of curvature (408).
